I would pick EveryDay Shooter ....... but haven't played any of them though. That and PAIN are the only 2 smaller games that I have a real interest in.

I bought Everyday shooter for $5 and was pretty impressed... closest thing to abstract art that I've seen in a video game, plus fun and challenging to play! I highly recommend...

Flow is a fun and relaxing experience. Very good use of Sixaxis controls.

Calling all Cars is a very accessible and fun multiplayer party game... highly recommend

I just wish they dropped price on Super Stardust HD too....
