Great edition to the GTA series although it has some slight problems. Still it's an awesome game overall
Guns are great and of course fun to use. If you don't have a gun with you and are only using your fists then it isn't the most fun ever. But with a gun or two it's awesome. Rockstar said the aiming sytem this time around would be right on the mark but unfortuanately they were wrong. Although it is improved from the last games it still doesn't give you full control on who your trying to aim at and it might take you 8 seconds until you final are aiming at the right target and this could easily cost you your life dealing with the police.
Sound is great. It's voice acting is better than any other of the GTA games because of of Nikko. If you were to ever listen to his lines then for many of them I think you would find them quite funny although Nikko doesn't try to make them jokes. But I can tell Rockstar wanted them to be.
This is a game reccomended to shooter, racing, hardcore GTA fans, or for people trying it out for the first time which should be a blast. Most 360 owners that can by M games probabaly already have the game so if you don't then what the hell are you waiting for!
