A selection that I'd recommend:
Don't Rest Your Head
You're an exhausted insomniac and you're slowly going mad. Oh and something's going to eat you if you ever go to sleep.
3:16 - Carnage Amongst The Stars
You're a Space Marine charged with protecting the human race from all possible threats: the best way to do that is to visit every planet in the universe and kill anything and everything that moves.
For some reason or another, your soul has been stolen, sold, or has rotted away. Now it's time to get it back, and you can do that in several different ways: Grow another, buy/steal someone else's, or eat ghosts.
Oh dear lord, I don't know how to explain it. Google it and check it out.
You solve a mystery - but instead of the GM having a mystery and the players solving it, the GM plants "clues" and the players decide what they mean.
The Shotgun Diaries
You're one of six survivors in a zombie apocalypse. You're only really good at one thing. You're either Strong, Fast, Clever, Dangerous, Sneaky or Useless (Well. If you're useless you aren't good at anything.) If you're alone, you can only ever perform actions that fall under the single word that describes you (if you're the Fast survivor, all you can do is run). If you're not alone, you get dice from your teammates to help you not die.
Kobolds Ate My Baby
You're a fuzzy little Kobold with a mouth bigger than your head. You like to eat... well, anything really, but fresh babies are your favorite. You need to raid the nearby farm and steal some fresh babies for KING TORG (all hail King Torg!), the King of the Kobolds, and if you're lucky you might snag a snack for yourself. You'll battle chickens, cows and farmers on your quest, and hopefully not drink too much soda.
I think that should do for now!
