Vice City is the only GTA I've ever really played, and it's awesome. Sometime I might buy a PS2 just to play Vice City (and Katamari Damacy :P).

I think that Vice City is the best GTA title yet.

I only liked 4. Dunno why. I've played others, but they seemed to be trying too hard to be "urban", from what litle I remember. At least, San Andreas. I don't really remember Vice City at all.
