Amazon’s Deal of the Day is the 360 version of Star Wars: The Force Unleased. At $10, it now fits our criteria from rent to buy. It’s a frustration that’s worth the $10–if you’re into that.
So far, Dawn of War II is my PC Game of the Year. You can enjoy it this weekend for $25 from Steam (I should be getting paid by Valve.) The Company of Heroes games are discounted too.
