Guitar Rock Tour isn't all about the guitar, either. There's also a drum game mode, which has you playing the same songs. Drums are very, very tough to get right; in fact, playing drums was frustrating enough to make me give up after a while, and I know it's not just me, because others who I've played the game with voiced the same complaint. I think Gameloft needs to rework this somehow in future installments of this game to make it a little more forgiving, especially on easy mode.

The more successful you are, the more awards and rewards you're given--gold stars for good work, essentially. Near as I can tell, there isn't any "unlockable" content like new guitars or costumes, as there is in Guitar Hero, for example; you have to play gigs successfully in order to unlock all the songs included with the game, though.

One of the big hooks that Tap Tap Revenge offers--besides its free price tag--is access to additional downloadable songs (in Tap Tap Revenge's case, for free, just like the game). Downloadable songs have also been a huge draw for the console versions of Rock Band and Guitar Hero, which charge users money for additional tracks. But what you see is what you get with Guitar Rock Tour. I'd love to see downloadable content made available for this game.

As unoriginal in concept and as mercilessly imitative as Guitar Rock Tour is, I find the game to be really well-executed and lots of fun to play. It's certainly worth the price, and one of the best music games to make it to the iPhone so far.

Guitar Rock Tour is compatible with any iPhone or iPod touch running the iPhone 2.x software update.
