Maybe Halo2...but this is what IGN said...
Gran Turismo 4
Publisher: Sony Computer Entertainment America
Developer: Polyphony Digital
Genre: Racing Simulation
Release date: Summer 2004
The racing game that literally changed the way developers design racing games is back for a fourth North American appearance. While we're all aware of the game's 500-plus cars, the amazingly scenic photo-realistic graphics, the new courses, and the heightened AI, what's really going to make GT4 soar, we think, is the online play. With GT Prologue giving us a little hint of what's to come, the six-player online games should be remarkable. Will the game use the hard disc drive also? It's very possible. We wouldn't count it out. Look for GT4 to probably hit retails stores in summer 2004 (that is, if we're lucky).
