with my 360 version I found that the game looks like ASS, prepare to be severely disappointed when you get it
annoying shimmering all over the place when outside that distracts you when you try to view things away in the distance (there's a bridge and it's so rough around the edges I can't believe it), unimpressive character models, environments and objects, some really, REALLY bad looking set pieces... only the facial animation in cutscenes and the lighting looks good at times, for the rest it's an Xbox game in HD
apart from that it's the same kind of game as GTA III, only with more emphasis on developed film-like cutscenes... this aspect is really good, I love what Rockstar is doing and they're once more at the top of their game
and one character calls another a cigarillo! take that GAF queers, muhahahahahahaha
