Grand Theft Auto III was a phenomenon. Released in October 2001 for the PlayStation 2, it revolutionized open-world gaming with its seamless 3D city, emergent gameplay, and mature narrative. What many don't realize is that Rockstar's North studio originally developed GTA III on Sega Dreamcast development kits. As former Rockstar technical director Obbe Vermeij later revealed: "The first months of development of GTA 3 (back in 99/00) were done on the Dreamcast. For commercial reasons we switched to PS2. At the time we did think it was technically possible to pull it off on the DC." A partnership with Sony and the Dreamcast's struggling commercial prospects led to the switch, and a legendary console missed out on a system-selling killer app.

However, to fit within the Dreamcast's memory constraints, textures are aggressively compressed during conversion. As a result, while the game world is fully intact, texture detail is noticeably lower than other versions. The iconic "trails" motion blur effect from the PS2 version is also absent, as the Dreamcast cannot efficiently render this post-processing effect.
