Honestly, I'm VERY satisfied with this game. Sure they didn't do too much different than GTAIV, but what they did do was effective and it seems like they really fine-tuned the game with this one. I remember GTA IV they tried to show off "oh you can do this and that" in the missions, but you'd only use it for that mission, and there was no outside purpose for it. In this one it seems that the skills actually prove to be a bit useful.
