Pretty good if you like RTS games; more complex than Civ, but not overbearing even for those of us that aren't RTS hxc gamers.

This is now free, so there's no reason not to own it.

This is an obvious buy; Portal 2 has probably been one of my most anticipated game release of the year, second only to Mass Effect 3 when that finally comes out.

The gameplay is a little easier than I anticipated, considering all the practice you get from playing through the original Portal, but it's still hella fun. I'm shooting through co-op with my brother next week and hope it's a bit more difficult.
