Company of Heroes at the minute. Picked it up in the recent Steam sale. I'm only on mission 9 of the first campaign, and I've been playing it for 8 hours. It's a long game...
Fantastic game, haven't played that in a long time, but some great memories
Just completed RAGE, now for WH 40k: DoW2, bloody amazing, can't believe i've deprived myself of it.
