I rented GRAW just recently and I was pleasently suprised at how good the game was. Reviews all over the place gave this game really good reviews, but mainly just because of the graphics; or so it seemed. This is my review for IMO the best 360 game to date; Tom Clancy's Ghost Recon: Advanced Warfighter.
Graphics: 10/10. Anyone who has seen this game knows the graphics are amazing. The character models and enviroments look great and the explosions are super pretty. This is most definitely the best looking 360 out right now. Really I don't understand why Mexico seems so deserted, though, but you'll forgive it because of great gameplay.
Sound: 8.5/10. Pretty good voice acting, but it's nothing too special. The AI chit-chats too here and there, but there's nothing too big. The explosions sound good, though, and the sound of the guns are well done.
Control: 7.5/10. Like most Ghost Recon games, the control is a bit strange, but being on a 360 controller, it's even harder. There are several things you need to learn and it will take quite awhile to get used to. It definitely makes the game harder than it really should be.
Fun: 9.5/10. I recently played the online demo of this game at the Xbox Live Marketplace, but I haven't played it yet on the full version. I thought even the demo was playable for hours just because it in my opinion is that fun of a game. You can also play Co-Op online or offline on the single player missions, which makes this game worth buying just for that. The learning curve may take up to an hour or so, but once you get used to this game, you won't put it down. It is also a VERY realistic game, 1-3 shots and you are dead. This is a must buy for any 360 owner.
