Wait. Wait this is really fun somehow.

Papers, Please is definitely a game that you wouldn't expect to be very fun, but it is.

Zafehouse Diaries is one you wouldn't expect to be fun unless you're into that kind of game.

DeathSpank

I've loved DeathSpank for a long time. It's really great.I absolutely love DeathSpank.

Hotline Miami

I played a flash game several years ago that played exactly like Hotline Miami. The guy who made that game also made some other top-down style game where you play as a medieval knight killing monsters or some such. Playing Hotline Miami just made me want to go play those old flash games again, but I couldn't find them ;_;
