Nothing today that interests me and I don't already have. Maybe I'll pick up something cheap that isn't on a daily sale. NightSky looks pretty good, I also really want Jamestown, but I feel like it might be going on a daily sale some time soon.
I've enjoyed Darksiders, Super Meat Boy, Battlefield: BC2, PvZ, and all of the Half-Life games, and would recommend them to anyone who hasn't tried them. Resident Evil 5 and Magicka are also really good, but each has issues that may make the game less fun for some.
