Topic is pretty self explanatory.
I've been playing a lot of Sim City 4 and The Binding of Isaac. Of course I've been making time for Counter Strike (I always do), and I borrowed Pikmin 2 off of a buddy of mine and have been playing that. I also got The Swapper on Steam recently and as far as puzzle games go it's pretty great so far. The puzzles are fantastic, but what really strikes me is the atmosphere.
What about you?
