You're nuts.. GTA4 was the best. Vice City was better than SA. SA had a good story and was fun but sh*t was kind of like a RPG mixed in with a FPS.
GTA 4 is sh*t, hands down the sh*ttest GTA game of all time, give me GTA SA/Vice City graphics anyday of the week if it means we will never have another GTA game like GTA 4.
Vice City would probably be my favourite if it was longer.
