I recently got all the Riddick games, Dead Space, Left4Dead 2 and GTA IV for $60 Canadian on STEAM. That was pretty much all I wanted to buy anyway, lol.
GTA IV was like 7 bucks, same with Dead Space, and all the games were fairly new. For that price I don't even mind buying single player games. I only got GTA IV to make videos anyway. (like this one: http://www.youtube.com/watch?v=rzfbX8veikg)
The specials on D2D don't seem as good from what I saw.
