The PlayStation 4 features two graphics [[Application programming interface|API]]s, a low level API named ''GNM'' and a high level API named ''GNMX''. Most people start with the GNMX API which wraps around GNM and manages the more esoteric [[Graphics processing unit|GPU]] details in a way that's a lot more familiar if users are used to platforms like [[Direct3D]] 11. A lot of work was put into the move to the lower-level GNM, and in the process the tech team found out just how much work DirectX does in the background in terms of memory allocation and resource management.<ref name="apis">{{cite web|url=http://www.eurogamer.net/articles/digitalfoundry-how-the-crew-was-ported-to-playstation-4 |title=How The Crew was ported to PlayStation 4 |publisher=Eurogamer |author=Richard Leadbetter |date=July 19, 2013 |accessdate=January 14, 2014}}</ref> |

⚫ | The [[Software Development Kit]] (SDK) is based on [[LLVM]] and [[Clang]]. Sony is using LLVM/Clang as its PlayStation 4 CPU compiler due to its highly conformant [[C (programming language)|C]] and [[C++]] front-ends, great [[C++11]] support, excellent diagnostic messages, fast compilation times, and excellent code generation. According to Sony, [[video game developer|game developers]] are loving the compiler toolchain except when it comes to the area of [[debugging]].<ref>{{cite web|url=http://www.phoronix.com/scan.php?page=news_item&px=MTU1MTY|title=[Phoronix] Why Sony Is Using LLVM/Clang On The PlayStation 4|publisher=Phoronix.com|accessdate=17 November 2014}}</ref> |

It is named "Dynamic Menu" because it is a new menu on the main menu screen and it's dynamic. The menu actually changes depending on what the users are doing with their PlayStation 4 to make it as simple to navigate as possible. Essentially the dynamic menu is this menu that constantly changing to give the users new information that might be relevant for them, that might make it easier for them to navigate, but most importantly, it is the menu that alters itself so that there's a little time as possible between the users putting in a game and they playing a game.<ref>{{cite web|url=http://www.howcast.com/videos/515524-what-is-the-dynamic-menu-ps4-faqs/|title=What Is the PlayStation 4 Dynamic Menu?|work=Howcast}}</ref> |

PlayStation 4's user interface attempts simplicity as a priority. On the PS4, the main place for entertainment options of the users, the Content area, is prominently displayed with large square icons on a horizontal line arranged by the most recently used. Press Down and users can scroll through this gamer newsfeed in an alternating, brick-like formation reminiscent of social media site [[Pinterest]]. Many other main objects will display additional information when having the cursor selected on them. A game may have news updates or advertisements for its downloadable content. Moving down the Content area, whatever games users have played receives a tile along with a number of mandatory items like the Live from PlayStation and the Internet Browser applications. Above Content icons is the Function area where users will find the [[PlayStation Store]] and other icons such as Notifications and Settings. Like the Content area, when an item is hovered over but not fully clicked on, a brief preview or content will be displayed, except above the icon line instead of below. Most of the Function area is self-explanatory and should take even a casual gamer very little time to become accustomed to it. Nevertheless, while users will find everything they want to play in the Content area, there is plenty on display they may never ever touch. Content icon customization and options on how to sort them would give players a way to mold the display to better suit their needs.<ref>{{cite web|url=http://www.psu.com/feature/21866/PlayStation-4-Review--The-User-Interface|title=PlayStation 4 Review: The User Interface|work=PlayStation Universe}}</ref> |

===Augmented Reality=== |
|||
The [[augmented reality]] application, the PlayRoom comes pre-installed with the PlayStation 4 console. It was demonstrated at [[E3 2013]] and utilizes the Sony [[PlayStation Camera]] technology. According to Sony, it is a "fantastically fresh augmented reality entertainment experience", which has been created by combining the light orb located on the front of [[DualShock 4]] controller with the PlayStation Camera. Players are allowed to produce a small floating robot called Asobi, who interacts with the players, scans their faces and shoots fireballs. Once the PlayStation Camera identifies the player with the help of the light bar on the front, a flick on the touchpad of the DualShock 4 controller brings up the augmented reality Bots function of PlayRoom, which creates the delusion that there are hundreds of little bots inside the controller, which can be released simply with a tap on the track pad that functions like the [[PlayStation Vita]]. PS4 owners can even view their [[smartphone]] or PlayStation Vita for drawing the object and flick it anywhere for the augmented reality Bots to play with. |
|||
Sony's decision to pre-install their augmented reality application on the PlayStation 4 console created a sensation in the market. This was an interesting move from the company's behalf, especially as this augmented reality application requires PlayStation Camera for functioning. Unlike the [[Kinect]] or the [[Xbox One]] of [[Microsoft]], Sony has decided to sell the camera separately and will not integrate the PlayStation Camera in the PS4, although there are rumors in the market suggesting that it was originally included, but the PS4 Camera was taken out only to beat the price tag of Xbox One.<ref>{{cite web|url=http://www.augmentedrealitytrends.com/ar-app/ps4-with-pre-installed-augmented-reality-game.html|title=PS4 with Pre-installed Augmented Reality Game|author=Nimrod Vardi|work=Augmented Reality Trends}}</ref> |

===Remote Play and second screen=== |
|||
[[Remote Play]] and [[second screen]] are some of the most attractive and anticipated features that the PlayStation 4 offers. Through Remote Play users can operate their PS4 with the help of the [[PlayStation Vita]] handheld game console. It isn't exactly a new feature for the PS4. The [[PlayStation 3]] and even [[PlayStation Portable]] supported it, allowing users to display their big screen on the small device via streaming, listen to music, use TV services and even play some games, providing the developers built it into the system.<ref name="exp">{{cite web|url=http://www.thesixthaxis.com/2013/11/28/remote-play-and-the-ps4s-second-screen-experience/|title=Remote Play And The PS4's Second Screen Experience|work=thesixthaxis.com}}</ref> However, the problem was PS3 only supported a "select" few titles and results were often laggy. On the other hand, Remote Play features a much better integration with the PS4.<ref>{{cite web|url=http://www.trustedreviews.com/opinions/ps4-remote-play-is-sony-s-killer-feature-and-it-s-not-even-new|title=PS4 Remote Play is Sony's killer feature and it's not even new|work=trustedreviews.com}}</ref> |
|||
Currently not all PS4 games allow the use of Remote Play, even though it is built into the system and supports most of the games, developers need to add extra options to enable Remote Play. Games which include the use of [[PlayStation Camera]] or [[PlayStation Move]] controller won't work with Remote Play. Players need to look for the Remote Play icon on the back of their game's box or go through instructions and manuals to check the compatibility of Remote Play. Furthermore, Remote Play lacks video broadcasts. It uses the same broadcast system to send input back, as a result users will not be able to broadcasts their videos. If they are playing a game on [[Split screen (computer graphics)|split screen]], it will show a split screen on the PlayStation Vita too. |
|||
Second screen can be used to display unique content when playing games that support this option, but it should not be confused with split screen. The second screen may be used to show extra contents for example maps, alternate camera angles, radar or even playbooks in sports games. Apart from PlayStation Vita, other [[mobile device]]s such as [[iPad]] or [[Android (operating system)|Android]] tablet can also be used as second screen.<ref>{{cite web|url=http://www.gamepur.com/guide/15910-how-use-remote-play-or-second-screen-ps4.html|title=How to use Remote Play or second screen with PS4|work=gamepur.com}}</ref> That comes in the form of both the official PlayStation App and game companion apps such as [[Knack (video game)|Knack's Quest]].<ref name="exp" /> |
|||
Furthermore, while PlayStation 4 cannot play PlayStation 3 titles directly, the [[PlayStation Now]] cloud-based gaming service can be used on PS4 consoles to allow gamers to play PS3 titles by streaming them over the [[Internet]].<ref>{{cite web|url=http://www.pcadvisor.co.uk/feature/game/playstation-now-release-date-price-supported-devices-features-uk-3497234/|title=PlayStation Now release date, price, supported device and features: PS Now reaches open beta|last=Martin|first=Chris|website=PC Advisor|date=July 16, 2015}}</ref> |
|||
===Social features=== |
|||
A heavy emphasis on social features has been placed by Sony on the PlayStation 4 console, loading up the PS4 with a number of share-centric apps and features. The [What’s New] feature, which allows users to check out their friends' latest activities via a landing page full of their pictures, trophies and other recent events, is an easy way to find out what friends have been up to. On the other hand, a cross-chat feature dubbed [Party Chat] is a interesting way to keep in touch, whether users are fragging or questing. Sony has taken a page from [[Microsoft]]’s book and added this new feature, which gives gamers the ability to chat with other friends whether or not they’re playing the same title. |
|||
In the world according to Sony, the PlayStation 4 generation is as much about social interaction as it its mind-blowing graphics. The PS4’s sharing capabilities adds another layer to console gaming. PS4 owners are able to capture or livestream the gameplay with a simple button touch. They can record up to 15 minutes of their latest gaming exploits with a quick press of the Share button on the controller. Footage can be shared on [[Facebook]] or [[Twitter]]. They also have the ability to broadcast their gameplay in real time to Twitch and [[Ustream]] in addition to recording videos.<ref>[http://www.tomsguide.com/us/ps4-vs-xbox-one,review-1970-6.html PS4 vs. Xbox One (2013): Which Console Wins?]</ref> |
|||
There are also other social features such as community creation. Some of them are introduced via system updates. Favorite Groups is a new section within the Friends app, and acts as a way to quickly access other people a user plays with most. This feature is aimed at making it easier and faster to get into a game session with friends. On the other hand, communities are new hubs that can be formed around shared interests like games, activities, or play styles. There also exist other smaller social features on PS4, such as the ability to message a friend with a request to watch their gameplay live and the use of stickers during messaging.<ref>[http://www.slashgear.com/ps4s-software-update-3-00-beta-launches-new-features-detailed-02400453/ PS4’s software update 3.00 beta launches, new features detailed]</ref> |
|||
===Multimedia features=== |
|||
[[DVD]] and [[Blu-ray]] movie playback were first supported out of the box by the [[PlayStation 2]] released in 2000 and the [[PlayStation 3]] released in 2006 respectively. On the other hand, Sony's PlayStation 4 console could not play [[Blu-ray]] or [[DVD]]s out of the box. Gamers who buy the PS4 on launch day will have to download an update from the Internet before watching movies on disc.<ref>{{cite web|url=http://www.mirror.co.uk/news/technology-science/technology/sony-playstation-4-fans-shocked-2640750|title=Sony PlayStation 4 fans shocked to find PS4 won't play DVDs or Blu-ray out of the box|last=Smith|first=Mikey|date=October 26, 2013|website=Mirror}}</ref> After this system software update and the activation of the video-playing capability over the Internet it will be able to play DVDs and Blu-Ray movies, but it still cannot read [[audio CD]]s. A possible reason for this is that Sony wanted users to join its [[Music Unlimited]] and [[Video Unlimited]] cloud services, which launched at the same time the PlayStation 4 was released,<ref>{{cite web|url=http://www.theregister.co.uk/2013/11/01/playstation_4_faq/|title=Here's what YOU WON'T be able to do with your PlayStation 4|last=McAllister|first=Neil|date=November 1, 2013|website=The Register}}</ref> although Sony later added [[Blu-ray 3D]] support for the console via a system update.<ref>{{cite web|url=http://www.techradar.com/us/news/gaming/consoles/you-can-watch-3d-blu-rays-on-your-ps4-right-now-1259494|title=You can watch 3D Blu-rays on your PS4 right now|last=Langley|first=Hugh|date=July 29, 2014|website=TechRadar}}</ref> |
|||
Users can also use the Media Player application to enjoy videos, photos and music that are saved on USB storage devices or media servers. The following file formats are supported. In order to successfully play various videos, music and movies on PS4, they needed to be converted to PS4 recognized formats as below:<ref>{{cite web|url=http://www.hivimoore.com/2015/06/play-hd-video-movie-on-ps4/|title=Can PS4 play MKV, AVI, VOB, M4V, M2TS, H.265, WMV, FLV, Tivo videos?|last=Li|first=Sharon|date=June 17, 2015|website=Hivimoore}}</ref> |

The initial version of the system software for the PlayStation 4 is 1.01 as pre-installed in the original consoles. Support for the [[Remote Play]] and [[second screen]] experiences were added in version 1.50, which was launched on the same day the PlayStation 4 console itself was released in [[North America]] on November 15, 2013,. Both features are accessible from the [[PlayStation Vita]] console by using its PS4 Link application, and the second screen functionality is also accessible from [[smartphone]]s and [[Tablet computer|tablet]]s through the [[PlayStation Mobile]] app. It is also able to record or share video clips as well as broadcasting gameplay to [[Twitch.tv]] or [[Ustream]].<ref>{{cite web|url=http://www.playstationlifestyle.net/2013/10/25/ps4-1-50-system-update-launches-day-1-includes-ps-vita-remote-play-gameplay-sharing-more/|title=PS4 1.50 System Update Launches Day 1; Includes PS Vita Remote Play, Gameplay Sharing, More|work=PlayStation LifeStyle}}</ref> It supports [[Blu-ray]] and [[DVD-Video]] playback, and version 1.60 released on February 4, 2014, improves DVD playback.

The PlayStation 4 system software is the updatable firmware and operating system of the PlayStation 4.
The system software is a Unix-like operating system. The process of updating the system is almost identical to that of the PlayStation Portable, PlayStation 3, and PlayStation Vita. The software may be updated by downloading the update directly on the PlayStation 4, downloading it from the user's local Official PlayStation website to a PC and using a USB storage device to transfer it to the PlayStation 4, or installing the update from game discs containing update data.
Technology
System
The native operating system of the PlayStation 4 is Orbis OS, which is a fork of FreeBSD version 9.0 which was released on 12 January 2012.[5][6] That FreeBSD is being used over Linux is in part due to its more liberal licensing. Furthermore, the PlayStation 4 is x86-64 based now rather than Cell-based (as was the PlayStation 3), which makes it easier to use FreeBSD.[7]
The PlayStation 4 features two graphics APIs, a low level API named GNM and a high level API named GNMX. Most people start with the GNMX API which wraps around GNM and manages the more esoteric GPU details in a way that's a lot more familiar if users are used to platforms like Direct3D 11. A lot of work was put into the move to the lower-level GNM, and in the process the tech team found out just how much work DirectX does in the background in terms of memory allocation and resource management.[8]
Another key area of the game is its programmable pixel shaders.[8] Sony's own PlayStation Shader Language (PSSL) was introduced on the PlayStation 4.[9] It has been suggested that the PlayStation Shader Language is very similar indeed to the HLSL standard in DirectX 11, with just subtle differences that were eliminated for the most part through pre-process macros.[8]
Besides the kernel and related components, other components included and worth mentioning are Cairo, jQuery, Lua, Mono, OpenSSL, WebKit, and the Pixman rendering library. Many of these are open-source software, although the PlayStation 4 is still not a very open console.[6][10]
The Software Development Kit (SDK) is based on LLVM and Clang. Sony is using LLVM/Clang as its PlayStation 4 CPU compiler due to its highly conformant C and C++ front-ends, great C++11 support, excellent diagnostic messages, fast compilation times, and excellent code generation. According to Sony, game developers are loving the compiler toolchain except when it comes to the area of debugging.[11]
Graphical shell
The PlayStation 4 uses the PlayStation Dynamic Menu as its graphical shell,[12][13][14] in contrast to the XrossMediaBar (XMB) used by the PlayStation Portable and PlayStation 3, as well as the LiveArea used by the PlayStation Vita and PlayStation TV. It is named "Dynamic Menu" because it is a new menu on the main menu screen and it's dynamic. The menu actually changes depending on what the users are doing with their PlayStation 4 to make it as simple to navigate as possible. Essentially the dynamic menu is this menu that constantly changing to give the users new information that might be relevant for them, that might make it easier for them to navigate, but most importantly, it is the menu that alters itself so that there's a little time as possible between the users putting in a game and they playing a game.[15]
PlayStation 4's user interface attempts simplicity as a priority. On the PS4, the main place for entertainment options of the users, the Content area, is prominently displayed with large square icons on a horizontal line arranged by the most recently used. Press Down and users can scroll through this gamer newsfeed in an alternating, brick-like formation reminiscent of social media site Pinterest. Many other main objects will display additional information when having the cursor selected on them. A game may have news updates or advertisements for its downloadable content. Moving down the Content area, whatever games users have played receives a tile along with a number of mandatory items like the Live from PlayStation and the Internet Browser applications. Above Content icons is the Function area where users will find the PlayStation Store and other icons such as Notifications and Settings. Like the Content area, when an item is hovered over but not fully clicked on, a brief preview or content will be displayed, except above the icon line instead of below. Most of the Function area is self-explanatory and should take even a casual gamer very little time to become accustomed to it. Nevertheless, while users will find everything they want to play in the Content area, there is plenty on display they may never ever touch. Content icon customization and options on how to sort them would give players a way to mold the display to better suit their needs.[16]
Augmented Reality
The augmented reality application, the PlayRoom comes pre-installed with the PlayStation 4 console. It was demonstrated at E3 2013 and utilizes the Sony PlayStation Camera technology. According to Sony, it is a "fantastically fresh augmented reality entertainment experience", which has been created by combining the light orb located on the front of DualShock 4 controller with the PlayStation Camera. Players are allowed to produce a small floating robot called Asobi, who interacts with the players, scans their faces and shoots fireballs. Once the PlayStation Camera identifies the player with the help of the light bar on the front, a flick on the touchpad of the DualShock 4 controller brings up the augmented reality Bots function of PlayRoom, which creates the delusion that there are hundreds of little bots inside the controller, which can be released simply with a tap on the track pad that functions like the PlayStation Vita. PS4 owners can even view their smartphone or PlayStation Vita for drawing the object and flick it anywhere for the augmented reality Bots to play with.
Sony's decision to pre-install their augmented reality application on the PlayStation 4 console created a sensation in the market. This was an interesting move from the company's behalf, especially as this augmented reality application requires PlayStation Camera for functioning. Unlike the Kinect or the Xbox One of Microsoft, Sony has decided to sell the camera separately and will not integrate the PlayStation Camera in the PS4, although there are rumors in the market suggesting that it was originally included, but the PS4 Camera was taken out only to beat the price tag of Xbox One.[17]
Remote Play and second screen
Remote Play and second screen are some of the most attractive and anticipated features that the PlayStation 4 offers. Through Remote Play users can operate their PS4 with the help of the PlayStation Vita handheld game console. It isn't exactly a new feature for the PS4. The PlayStation 3 and even PlayStation Portable supported it, allowing users to display their big screen on the small device via streaming, listen to music, use TV services and even play some games, providing the developers built it into the system.[18] However, the problem was PS3 only supported a "select" few titles and results were often laggy. On the other hand, Remote Play features a much better integration with the PS4.[19]
Currently not all PS4 games allow the use of Remote Play, even though it is built into the system and supports most of the games, developers need to add extra options to enable Remote Play. Games which include the use of PlayStation Camera or PlayStation Move controller won't work with Remote Play. Players need to look for the Remote Play icon on the back of their game's box or go through instructions and manuals to check the compatibility of Remote Play. Furthermore, Remote Play lacks video broadcasts. It uses the same broadcast system to send input back, as a result users will not be able to broadcasts their videos. If they are playing a game on split screen, it will show a split screen on the PlayStation Vita too.
Second screen can be used to display unique content when playing games that support this option, but it should not be confused with split screen. The second screen may be used to show extra contents for example maps, alternate camera angles, radar or even playbooks in sports games. Apart from PlayStation Vita, other mobile devices such as iPad or Android tablet can also be used as second screen.[20] That comes in the form of both the official PlayStation App and game companion apps such as Knack's Quest.[18]
Furthermore, while PlayStation 4 cannot play PlayStation 3 titles directly, the PlayStation Now cloud-based gaming service can be used on PS4 consoles to allow gamers to play PS3 titles by streaming them over the Internet.[21]
Social features
A heavy emphasis on social features has been placed by Sony on the PlayStation 4 console, loading up the PS4 with a number of share-centric apps and features. The [What’s New] feature, which allows users to check out their friends' latest activities via a landing page full of their pictures, trophies and other recent events, is an easy way to find out what friends have been up to. On the other hand, a cross-chat feature dubbed [Party Chat] is a interesting way to keep in touch, whether users are fragging or questing. Sony has taken a page from Microsoft’s book and added this new feature, which gives gamers the ability to chat with other friends whether or not they’re playing the same title.
In the world according to Sony, the PlayStation 4 generation is as much about social interaction as it its mind-blowing graphics. The PS4’s sharing capabilities adds another layer to console gaming. PS4 owners are able to capture or livestream the gameplay with a simple button touch. They can record up to 15 minutes of their latest gaming exploits with a quick press of the Share button on the controller. Footage can be shared on Facebook or Twitter. They also have the ability to broadcast their gameplay in real time to Twitch and Ustream in addition to recording videos.[22]
There are also other social features such as community creation. Some of them are introduced via system updates. Favorite Groups is a new section within the Friends app, and acts as a way to quickly access other people a user plays with most. This feature is aimed at making it easier and faster to get into a game session with friends. On the other hand, communities are new hubs that can be formed around shared interests like games, activities, or play styles. There also exist other smaller social features on PS4, such as the ability to message a friend with a request to watch their gameplay live and the use of stickers during messaging.[23]
Multimedia features
DVD and Blu-ray movie playback were first supported out of the box by the PlayStation 2 released in 2000 and the PlayStation 3 released in 2006 respectively. On the other hand, Sony's PlayStation 4 console could not play Blu-ray or DVDs out of the box. Gamers who buy the PS4 on launch day will have to download an update from the Internet before watching movies on disc.[24] After this system software update and the activation of the video-playing capability over the Internet it will be able to play DVDs and Blu-Ray movies, but it still cannot read audio CDs. A possible reason for this is that Sony wanted users to join its Music Unlimited and Video Unlimited cloud services, which launched at the same time the PlayStation 4 was released,[25] although Sony later added Blu-ray 3D support for the console via a system update.[26]
Users can also use the Media Player application to enjoy videos, photos and music that are saved on USB storage devices or media servers. The following file formats are supported. In order to successfully play various videos, music and movies on PS4, they needed to be converted to PS4 recognized formats as below:[27]
- Videos: MKV, AVI, MP4, MPEG-2 TS, AVCHD (.m2ts, .mts)
- Photos: JPEG (DCF 2.0/Exif 2.21 compliant), BMP, PNG
- Music: MP3, AAC (M4A)
History of updates
The initial version of the system software for the PlayStation 4 is 1.01 as pre-installed in the original consoles. Support for the Remote Play and second screen experiences were added in version 1.50, which was launched on the same day the PlayStation 4 console itself was released in North America on November 15, 2013,. Both features are accessible from the PlayStation Vita console by using its PS4 Link application, and the second screen functionality is also accessible from smartphones and tablets through the PlayStation Mobile app. It is also able to record or share video clips as well as broadcasting gameplay to Twitch.tv or Ustream.[28] It supports Blu-ray and DVD-Video playback, and version 1.60 released on February 4, 2014, improves DVD playback. Version 1.60 also adds support for Pulse Elite wireless headsets.[29] Version 1.70 released on April 30, 2014, adds a number of new features, such as the addition of a rich video editor called ShareFactory that offers users the tools to combine, edit and personalize captured video clips. This update also adds the abilities to share video clips and screenshots while streaming, and to copy video clips and screenshots to USB storage.[30] Version 1.75 released on July 29, 2014, further adds the support for playback of Blu-ray 3D. It also improves the sound quality during 1.5-speed playback with Blu-ray and DVD video.[31] Version 1.76 released on September 2, 2014, came with minor changes and was the last update until version 2.0.[32]
Released on October 28, 2014, version 2.0 is a major upgrade to the PlayStation 4 system software. Among the features introduced is Share Play, which allows PlayStation Plus users to invite an online friend to join their play session via streaming, even if they do not own a copy of the game. Users can pass control of the game entirely to the remote user, or partake in cooperative multiplayer as if they were physically present.[33][34] This version also adds a YouTube app and the ability to upload video clips to YouTube, and users can now play music stored on USB storage devices. Also, with the support for custom themes and the ability to change the background color, users can set themes for home screens and function screens for each user in this version.[35] Version 2.50 released on March 26, 2015, adds a suspend/resume feature to allow players to jump in and out of games with the PS button, and games are suspended in the low-power Rest Mode instead of closing completely. This version also allows the console's hard drive to be backed up or restored to a USB flash drive.[36]
Released on September 30th, 2015, version 3.0 is the most recent major upgrade to the system. It introduces "entirely new features" and user-interface enhancements. Among the new features is the ability to share videos directly to Twitter, a dedicated PlayStation Plus section, tweaks to the interface for streaming on YouTube, improvements to social features such as messages and group creation, and the ability to save screenshots as PNGs. An increase in online storage capacity from 1 GB to 10 GB is also introduced for PlayStation Plus Members. Sony states that this update will create "new ways to connect with friends and players around the world, expanding the social capabilities of the system even further".[37]
