"Grand Theft Auto III" (GTA 3) is an action-adventure game developed by Rockstar North (then known as DMA Design) and published by Rockstar Games. It was released on October 22, 2001, for the PlayStation 2 console. The game is set in the fictional Liberty City, which is based on New York City. GTA 3 was critically acclaimed and commercially successful, becoming one of the best-selling video games of 2001. It's considered a pivotal title in the Grand Theft Auto series, marking a significant shift towards 3D gameplay. Sega Dreamcast The Sega Dreamcast, released in 1998, was Sega's first console to connect players online. Despite its innovative features and critically acclaimed games, the Dreamcast was discontinued in 2001, largely due to the success of Sony's PlayStation 2 and the impending release of Microsoft's Xbox and Nintendo's GameCube. Grand Theft Auto III and Sega Dreamcast There was a notable situation where Rockstar Games considered or hinted at developing a version of GTA III for the Dreamcast. In an interview and in some promotional materials around the time of GTA III's announcement, there were mentions of possibly developing the game for the Dreamcast. However, this never came to fruition. The reason was largely attributed to Sega's decision to discontinue the Dreamcast in the face of the PlayStation 2's dominance and the financial struggles of Sega at the time. CDI and Confusion The term "cdi" could be a confusion or misremembering of platforms. There was a console called the Philips CD-i, which was released in the early 1990s. It had some licensed games based on popular franchises, but it was not associated with GTA III. Another possibility is that "cdi full" refers to a specific version or package of the game, possibly including its full soundtrack or additional content, but this seems less likely. Conclusion The history of "Grand Theft Auto III" and its non-release on the Sega Dreamcast remains an interesting footnote in the story of both Rockstar Games and Sega. The scenario with GTA III showcases the competitive and rapidly changing landscape of the video game industry in the early 2000s, where platform strategies and game development cycles could lead to intriguing 'what ifs'. Despite the Dreamcast's innovative spirit and some excellent games, it ultimately did not host a GTA III game, a fact that might have influenced gamers' and developers' experiences with both the console and the game series.
