This game is a next-gen masterpiece. The single player is solid, and the multi-player is amazing.
Graphics - The graphics in GRAW are mind-blowing. The graphics in the single player and the ones in the multi player are different. The single player graphics look a bit better, and they look a little better, more realistic. The multi-player's graphics are amazing, and you can really see it on levels like 'Rocky Cove' and 'Fishing Village'. Overall, the graphics are stunning no matter what game mode you play it on.
Sound - The sound on GRAW is great also. The singleplayer gives you a sense of realism, having your team with you and communicating. The only problem i had was the rare bad voice acting, but other than that, it was great. The sound on guns and explosions were amazing, and were intense.
OVERALL : Overall, this game is pretty amazing. The singleplayer is amazing, and is actually quite difficult, even on the normal difficulty. The multi player is really where its at, and it will keep you coming back for more. This game so far is the "Halo" of the 360, with it's popular online play. This game is a definite pickup, especially if your tired of some online shooters like PDZ and Quake 4.
