So far, I picked up:
Walking Dead Season 2
Wolf Among Us
Ikaruga (I suck at this game!!!)
Metal Slug 3 (got Stephen a copy, too)
Metal Gear Rising
I'm holding out for Cave Story+. It's at 6.99 now, but I think it may drop even more by the end of the sale.
Also making it a point to play more of my Steam games. Finished Braid last night, played Hotline Miami for an hour and hated it (really want to love it, but the controls are pretty shitty), and I'm playing Fez when I'm around my home computer.
