This game is magnificent! Absolutely gorgeous and I haven't played the story mode yet.
The graphics are incredible and the controls have improved greatly since San Andreas. As a GTA fan I loved that they gave us a better over-head view for when you're in a gunfight.
The only problem I have with the game is the speed of the characters. Every animation has to go through before you can do anything. To climb over a gate i have to watch the character jump, pull himself up, then hop over, land, and finally stand up. Which sucks online when you're in a heated battle because while you're doing all of this, you are getting shot at and can't stop the animation. Same problem goes for jumping, it's so slow and you don't go anywhere which makes it useless. I really wish Rockstar made players able to speed up these animations.
