Somebody should go and buy The Ship. It's $5 and comes with two free full-game codes for bros.
The game is like an FPS FFA Hide and Seek meets The Sims. You're on a cruise ship, and you are a participant that must kill a certain target. Your identity is masked behind a passenger name, so act normal and you wont get caught. That said, you must also maintain yourself by eating food, socializing, shitting, showering, etc. You also can't kill where security guards will see you.
The game is pretty old now, but I still think it's graphic style is gorgeous. it's also the only game I've had fun as a spectator, since you play as a non-combatant and are allowed to walk around the ships (which are gorgeous.)
I personally don't own it, but I've played it at an internet cafe several years ago.
