What are your favorite iphone/ipad games?  I have this awesome game on my iphone called Beat Hazard Ultra.  It uses your music to power an asteroids type space ship game.  Each song on your iphone is a "track" that you need to clear.  Your firepower pulses to the beat of your music and you can get powerups that will increase the volume of the song.  So much fun...

Looks rad!! Classical shooter fun!

I liked the mobile version of RAGE: It was a three level rail shooter, first person kind of thing. Was it worth the dollars? Not sure but it satisfied my craving for the game before it came out on the consoles.

Have you heard of REPUBLIQUE? I know, both those look kinda like elaborate stuff, rather than quick fun, but hey...
