I wouldn't buy GTA for sure. It's a very popular franchise, but it doesn't appeal at all to me (I played GTA 3 and Vice City for a combined 5 hours on PS2, the game gets boring very fast). That's probably because I grew up with Nintendo games and therefore I am used to much more polished games. GTA really lacks in just every aspect of a game (controls, graphics, sound, AI, mission design etc.). What appeals to the masses is that the game lets you beat up innocent or not so innocent people whenever you want, lots of room to mess around with the stupid AI and such (Fable is the rpg-counterpart of GTA, don't flame me, that's just my opinion, but you have to admit that both games are kinda similar flawed).
