There's a great review at Eurogamer, they give it 9/10. Read it here:

Judging by the comments, there's a lot of people who didn't know about the game. I think that's PC-gamings biggest problem at the moment - there's a lot of great PC-titles around, but the press doesn't seem interested in covering them properly, so people get the impression it's all World of Warcraft and Football Manager and nothing more. I wish there was something to be done about this.
But I digress. Though the review at EG is falling off the front page alarmingly fast, it seems to have generated some extra interest. Which is good.
