I didnt say that everyone who plays it is retarded or plays it for violence. As I said some people may play a game for different reasons. But the main selling point of GTA for the most people isnt what you and some other people see in it.
I dont know much about GTA4. So it could be different. My personal experience with previous GTA games didnt express to me any form of creativity or art though.
I agree, the past GTAs mostly got by on their crude,irreverent humour, their somewhat notable acting performances, and their general willingness to let you kill/destroy and/or maim anything in sight.
Some of the stuff San Andreas was asking you to do (i.e. scare a hood into compliance by strapping him to the front of car and driving wildly) was innovative from a design standpoint, but the GTAs have had such poor controls and rampant performance issues that even the manner in which you complete these tasks isn't very fun.
Aside from that, the stories and social commentaries were never "deep" or poignant like the fans/press pretended,they were cynical, and mean spirited interpretations of Scarface. (and all the while, failing to communicate Scarface's point in any meaningful way)
Yet GTAIV looks different.
Certainly the typical GTA content is there, but Rockstar North has decided to tackle violence in a more mature,responsible manner.
By all (albeit hyperbolic) accounts, GTAIV, unlike its predecessors, is actually going to try to depict criminals and criminal behaviour in a more repulsive and harrowing manner. Rockstar appears to have done what it should have done three iterations ago;they made game that makes you think about the consequences of your actions. A game that's trying to get you feel something beyond mild amusement. Personally,I'd like to see how that goes.
I'm buying the PS3 version at launch.
