Really nice deal going on at humblebundle.com now.
"The bundle offers Dead Space, Dead Space 3, Medal of Honor, Burnout Paradise: The Ultimate Box, Crysis 2: Maximum Edition and Mirror's Edge on a pay-what-you-want basis. Meanwhile, for those who pay above the average donation, Battlefield 3 and The Sims 3: Starter Pack will also be available. The average donation is currently $4.67."
Deal ends in two weeks.
I don't know that my computer will run most of those, but for $5 it's worth a shot
