Really Impressive
I played through the first 10 levels or so of SP and while I haven't finished it yet, its right up my alley. The AI is smart and actually reacts to your use of time powers and the visuals are outstanding in the early levels. I think the story if cool too, but its not entirely clear and is somewhat separate from the game.
The time powers definitely add a new twist to the game that most games lack. I know that the press would rather play Halo or HL2 or COD4 again and that their opinions are influenced heavily by hype over substance, but this game is stellar. Its really worth a 9 but I am giving it a 10 because it needs more attention than it is sure to get...
