GamesRadar gave it a 9/10
Personally, I liked this bit of the review:
The biggest fear for GOW was being forced, by sloppy interpretation, on to a 360 controller. Not only doesn't this happen, but the ease of control and the sheer, stupid boost of enjoyment we got from the game, having previously been saddled with the 360 controller, is a slap in the face for everyone who's ever got it wrong. Everyone knows that the mouse and keyboard is the best combination for shooters, and although GOW came from a console, Epic's PC heritage has done the platform proud. The PC version is just plain better. Even the camera - the bane of the third-person shooter genre - doesn't cause any problems.
Sounds promising to me!
