Bioshock Infinite. 
I'll second the Tomb Raider suggestion.
Dark Souls. It will give you fever induced nightmares and cold sweats

Listen to Wu-Tang and watch Kung-Fu

Yes this. Though I am sure he bought something already.
Two hours is up... oh well. Binary Domain would have been my choice, you should be able to get it for $7.
I ended up being set on Tomb Raider and of course the GameStop next to my office (in an ultra shitty neighborhood), didn't have a used copy of it. At that point I was so feverishly delerious that I just said screw it and went home without anything. Probably worked out for the best. I fell asleep watching Dual Survival and sweat it out in bed, and sleep was really what I needed. Still feel like crap today, but not nearly as bad. I'll probably grab something later this morning though at a store with a better selection. Still may be Tomb Raider.
Oh and as to the other suggestions, I had Dark Souls once upon a time and pussed out after a while. Not sure I'm up for it. And if Binary Domain is that cheap I may grab it. I remember your impressions of it on a podcast. Gamestop is doing buy 2 get 1 free, so I may go the ultra cheap route and buy it with 2 other cheap Wii games or something.
Tokyo Jungle.
I think they're giving Binary Domain away for free these days. They may even pay you something to take it

Surprisingly enough I couldn't find a copy of Binary Domain. Maybe they've dumped it into the landfill with all the Atari 2600 ET cartridges.
