I liked Grand Theft Auto III way better than Grand Theft Auto IV and I probably played more of Vice City than any of the games. Boy, I hope they took the opportunity to fix the multitude of glitches in these games, though! I remember a bad one in GTA III where you can't complete the full game if you had save data already existing on your card, or something... happened to me.
Note to gamers: when someone shoots you in the face, they aren't "gay." They are "psychopathic."
