Saw was surprisingly good. The endings were kinda weak, but it was actually pretty intelligent. I was expecting a shitty movie cash-in game, but the puzzle gameplay was actually really solid. It really feels like they put some thought into the game.
Right now I'm playing Tomb Raider Anniversary, about 2/3 of the way through the game. Although I just rented Modern Warfare 2, so I'll be playing a lot of that for the next few days.
