Vampire Bloodlines @ $5 is always nice
Nothing really interesting me though. I already have all the ones that would interest me.
For those that want less "scary" games, the Indie Royale is ongoing: http://www.indieroyale.com/
4 correct games (if less hyped and known) for about $5 (price varies with demand):
- sanctum, Nimbus, ARES and Gemini Rue
