Bday coming soon (like Very Soon)

Since it's a pretty great tradition on this site to give a semi decent to really good game on your birthday to the community. Well I plan to participate, but I don't think I'll be able to do better than around a $10.00 US game. I know there are plenty of games that fit that category (within that price range though).
So here is my question, I will do it as a private through the forum, so who better to ask then forum users. What game in that price range would you love to see. I'm particular to games that most ppl ignore so they rarely show up on Steam Gifts. Obviously make sure you suggest a game you really would want.
I'm want to put up something others will really appreciate and get a kick out of.

Thanks for the suggestions.
