Everybody's been wanting Grand Theft Auto on GameCube? I don't remember people bitching that it's only on PlayStation 2. Vice City was overrated, yes. It was in no way better than Grand Theft Auto III. It only had very minor improvements, the frame rate seemed alot lower, and the sound track, while fitting, just didn't excite like the written from scratch GTAIII did.
But c'mon, GTAIII was a bloody brilliant game. At the time, the graphics were outstanding, the freedom and the land scapes were pretty damn impressive, and it was generally a very fun game to kick back to. GTA will forever be a huge game with the casual gamers, the 'cool' MTV kids, and so on. Which is quite sad, as the majority of them don't even play it for the missions or storyline.
I have such a friend, he owns both GTAIII and Vice City on PS2. Hasn't even come close to finishing them. He just used an Action Reply on both games to unlock the islands, and goes around on rampages.
