Obviously there's only so much immersion that you can achieve when you're pretending to play a guitar by tapping on the screen of your iPhone, but playing the tracks in the iPhone Rock Band works just like its console big brother in that every note you miss causes the music to be interrupted. However, where Rock Band pulls ahead of the pack of rhythm games on the iPhone is when it comes to overall immersion while you're playing the songs. After all, Tapulous has been through three revisions of Tap Tap Revolution, the latest of which we reviewed recently and includes an immense in-game store to buy new music to play along with a bunch of other features. I admit when we first got approached by EA about Rock Band I was skeptical.
