The FREE Super Hero Squad when you buy Xbox 360 uDraw Tablet deal is pretty good. I liked the first Super Hero Squad game pretty well. (It's a lot like the Lego games. Fun, but repetitive.)
I picked up Far Cry: Instincts (For the plain old XBox.) at a Target in Durham, NC (by Southpoint Mall) for $9.98 at lunch today.
It's actually for my brother, I don't even have an XBox.
