Even though I'll probably get flamed to death *dons his flame-shield for dramatic effect* I gotta go with every GTA game from 3 onward. I got GTA III when it first came out because I heard about how great it was from friends, etc. I played it for a week or so and it never really engaged me.
I did like that they had Michael Rappaport doing a voice for one of the characters though, he's an under-appreciated actor, but aside from that I found the game boring, repetitive, and simply gratuitous violence for the sake of violence.
So, a couple years go by and I decide to give the franchise another try, so I bought a copy of Vice City. Sure, it was nice to hear all the 80s toons in the game, but again it was more of the same. Gratuitous violence for its own sake, boring gameplay, and nearly broken controls if you had to shoot someone.
So, what did I do a couple years later? You guessed it, I picked up San Andreas at a pawn shop for 5 bucks and hated that game as well. I started occupying myself by making CJ as fat as I possibly could and giving him the biggest 'fro I could get rather than playing the missions since it was more fun, but even that failed to keep my attention long.
This time around I finally wised up, I did not(and will not) purchase GTA IV. The series is utter garbage and I am finally done with it.
On a side-note, two other games I got that I found to be gratuitous violence for the sake of violence games that I couldn't stand were Manhunt and The Suffering. Who knows, maybe I'm just too old school, maybe I expect my games to be more lighthearted and fun instead of M rated crapfests filled with gore, violence, and vulgar language for no other reason than just to sell the game.
These days I take great care before I lay down my money on an M rated game, I do research and try my best to make sure the game isn't just another game cashing in on being "edgy" simply to sell more units to teenage boys whose parents don't take the time to properly filter the media they digest.
