This is why I like Steam: the sales. I bought L4D this past weekend because it's a game that I'm not sure I'll play much but I figure is surely worth $25. I still have yet to play online but I'm just trying to get accustomed to it before I do.

I was waiting for a super deal on UT3 but a guy at work is willing to give me his copy or either sell it to me cheap (we haven't determined that yet).
