Graphics (10): This game has the best graphics I have ever seen. The masturful use of normal mapping, bump mapping, shadows, and light makes this game look incredible (even better than Doom 3 and Half-Life 2, the current graphics leaders in the gaming industry)! I don't know how more realistic it can get than this.
Gameplay (9): Have you ever wished while playing the first two Splinter Cells that Sam wouldn't be so nice and restrained? If so, than this is your game is for you! Sam Fisher no longer is restricted from killing enemies (besides in one or two of the Solo missions), and never is there a mission in which Sam is limited to a certain number of alarms before Mission Over. Some may argue that this cause for less stealth and more killing detracts from the stealth gameplay, but there is now a loadout choice at the beginning of each mission that allows you to choos "Stealth", "Assault", or "Redding's Recommendation" (usually a mix of the two). This great addition allows one to play the game as they want it, stealthily or aggressively.
Bottom Line (9.7): If you have enjoyed the Splinter Cell series, get this game. If you are even remotely interested in the stealth-action genre, get this game. If you are trying to decide which game to get right now, GET THIS GAME! This game is the best game ever seen on Xbox (it's the version I have played)! Get it, or Sam Fisher will come for you in the night.
