I'm kinda bored of these "let's play x" - threads by now, and imo we need to take this all to a one topic.

So, what games do you play actively?

My list:
Call of Duty 4 (best mp shooter since 1.6)
Toribash (therapeutic if you're tired/hungover)

I also have Medieval II and Company of Heroes installed which I do play time to time. Also a heap of those so called fundamental Steam games.
Not much of a powergamer meself.
