answer: Sony Computer Entertainment
context: Title: Hardware: Online Arena
  Passage: Hardware: Online Arena is an online multiplayer game that focuses on vehicular destruction using varying means such as missiles, lasers and machine guns.  The game was released for PlayStation 2 with the launch of online play for the console and was thus arguably the first online game for PS2.  The game was not a huge commercial success, selling very little.  To boost sales, the game was added onto the network access disk that came with the purchase of the network adaptor and, as a result, the game was one of the three most popular games played online during 2005, having over 200 users on at any one time.  GamesMaster Magazine said the game was, "A great indicator of the shape of things to come for PS2 online."
  Title: PlayStation 2 online functionality
  Passage: Selected games on Sony's PlayStation 2 video game console offer online gaming or other online capabilities.  Games that enable the feature provide free online play through the use of a broadband internet connection and a PlayStation 2 Network Adaptor.  Since the service has no official name, it is sometimes referred as either PS2 Network Play, PS2 Network Gaming, or PS2 Online.
  Title: PlayStation 2
  Passage: The PlayStation 2 (PS2) is a home video game console that was developed by Sony Computer Entertainment.  It is the successor to the PlayStation, and is the second installment in the PlayStation lineup of consoles.  It was released on March 4, 2000 in Japan, October 26, 2000 in North America, November 24, 2000 in Europe, and November 17, 2000 in Australia.  It competed with Sega's Dreamcast, Microsoft's Xbox, and Nintendo's GameCube in the sixth generation of video game consoles.
  Title: 4x4 Evolution
  Passage: 4x4 Evolution (also known as 4x4 EVO, codenamed Metal Crush 3) is a video game developed by Terminal Reality for the Windows, Macintosh, PlayStation 2 and Dreamcast platforms.  It is one of the first console games to have cross-platform online play where Dreamcast, Macintosh and PC versions of the game appear online at the same time.  The game can use maps created by users to download onto a hard drive, as well as a Dreamcast VMU.  All versions of the game are similar in quality and gameplay, although the online systems feature a mode to customize the players' own truck and use it online.  The game is still online-capable on all systems except for PlayStation 2.  This was Terminal Reality's only video game to be released for the Dreamcast.
  Title: Video game accessory
  Passage: A video game accessory is a distinct piece of hardware that is required to use a video game console, or one that enriches the video game's play experience.  Essentially, video game accessories are everything except the console itself, such as controllers, memory, power adapters (AC), and audio/visual cables.  Most video game consoles come with the accessories required to play games out of the box (minus software): one A/V cable, one AC cable, and a controller.  Memory is usually the most required accessory outside of these, as game data cannot be saved to compact discs.  The companies that manufacture video game consoles also make these accessories for replacement purposes (AC cords and A/V cables) as well as improving the overall experience (extra controllers for more players, or unique devices like light guns and dance pads).  There is an entire industry of companies that create accessories for consoles as well, called third-party companies.  The prices are often lower than those made by the maker of the console (first-party).  This is usually achieved by avoiding licensing or using cheaper materials.  For the mobile systems like the PlayStation Portable and Game Boy iterations, there are many accessories to make them more usable in mobile environments, such as mobile chargers, lighting to improve visibility, and cases to both protect and help organize the collection of system peripherals to.  Newer accessories include many home-made things like mod chips to bypass manufacturing protection or homemade software.

  Title: XLink Kai
  Passage: XLink Kai is a method developed by Team-XLink for online play of certain System Link compatible video games.  It enables players on the Nintendo GameCube, PlayStation 2, PlayStation 3, PlayStation Portable, Xbox and Xbox 360 to play games across the Internet using a network configuration that simulates a local area network (LAN).  It notably also allows original Xbox games to be played online again following the Xbox Live shutdown on April 21, 2010 (similar to that of Save Nintendo Wi-Fi for the Wii) and certain GameSpy titles such as "Saints Row 2" to be played online after the GameSpy network shutdown on May 31, 2014.
  Title: List of Xbox System Link games
  Passage: This is a list of original Xbox games that are compatible with the System Link feature, both released and unreleased, organized alphabetically by name.  Platinum Hits releases may not system link with non-platinum hits releases due to some Platinum Hits releases having Title Updates that will not link with older versions, and some games will not link with non updated versions if they have Title Updates applied, either through XBL or a softmod.  For Xbox 360 games, see List of Xbox 360 System Link games.  Some games allow more players if one Xbox acts as a Dedicated Server.  A Dedicated Server means one of the Xboxs hosts the others and you can't play on the host Xbox.
  Title: List of Xbox games compatible with Xbox 360
  Passage: This is a list of Xbox games that are compatible with the console's successor, the Xbox 360.  Microsoft ceased adding titles to the list in November 2007, so the list is considered final.  As of April 2010, original Xbox games no longer can be played online via the Xbox Live service, as it was ended for the original Xbox console.  However, online multiplayer still is possible through third-party LAN Tunneling programs that manipulate System Link, such as XLink Kai.  Downloadable content for these titles is not available via Xbox Live.  This includes the Xbox Originals downloaded on the Xbox 360 and any Xbox game running on the Xbox 360.
  Title: PlayStation 3
