Bought Amnesia for $5, installed that, checked it out. Was actually pretty surprised as to how well the laptop is running it. Cracking an easy 30 fps @ 720P with most stuff on medium or high including SSAO. The only things I turned off were AA and Parallax mapping. This should look beautiful on the tv, and best of all, I can leave the desktop at home.
The only other snag is from the minute I've played of it, a controller would probably be cumbersome. I'll probably have to try it myself, though it seems it would be better without.
