Grand Theft Auto (video game)
Grand Theft Auto is an action-adventure video game developed by DMA Design and published by BMG Interactive. It was first released in Europe and North America in October 1997 for MS-DOS and Microsoft Windows. It was later re-released on 12 December 1997 in Europe and 30 June 1998 in North America for the PlayStation. It is the first instalment of the "Grand Theft Auto" series, to be followed by 1999's "Grand Theft Auto 2". The series, which has led to five main entries and several special edition games over 16 years, has sold more than 150 million units as of September 2013. The story follows a group of criminals in three fictionalised versions of US cities as they perform bank robberies, assassinations, and other illegal activities for their respective crime syndicates.
Grand Theft Auto IV
Work on "Grand Theft Auto IV" began in November 2004, almost immediately after the release of "" (2004). Around 150 game developers worked on "Grand Theft Auto IV", led by core members of the team that previously worked on "Grand Theft Auto III" (2001). For the game, Rockstar used their proprietary Rockstar Advanced Game Engine (RAGE), which was previously used in "Rockstar Games Presents Table Tennis" (2006), in combination with the Euphoria game animation engine. Instead of pre-written animations, Euphoria uses procedural animation to control the way the player moves, enabling character movements to be more realistic. The Euphoria engine also enables NPCs to react in a realistic way to the player's actions. In one preview, a player knocked an NPC out of a window and the character grabbed onto a ledge to stop himself from falling. The game also uses middleware from Image Metrics to facilitate intricate facial expressions and ease the process of incorporating lip-synching. Foliage in the game is produced through SpeedTree.
