What is your favorite rhythm game for the iPhone/iPod touch? If it's not in the poll, please state it below. Mine is Tap Tap Revenge 2, with all my imported music. Edit: And sorry I couldn't fit the original Tap Tap Revenge, I ran out of options.
It's not an app store game because I don't like any of the rhythm games the app store has to offer, but my favorite rhythm game is Elite Beat Agents.
I like TTR2 the best mostly because of the polish and the tracks. It's a little too easy, though, with only three... frets? I dominate extreme, so...
