I already owned a xbox 360 guitar from my purchase of guitar hero 2, so I only bought the standalone game for $59.99. I can say with certainty that this game absolutely blows Guitar Hero 2 out of the water. The game consists of a scrolling fret board with 5 different notes that you must simultaneously press on your guitar. Higher note streaks add multipliers to your score. This song comes with a humongous 70 plus songs on the retail disc, plus more others through xbox live downloadable content. The game becomes very challenging on the expert level, but even beginners can rock out within minutes on the lower difficulties. The single player is pretty standard, but features slightly boring boss battles against legends like slash and tom morello, where you must use battle power-ups to make them fail. This battle mode is also featured in the multiplayer portion, but it is not fun to play. Online and offline multiplayer makes its way into this game, greatly adding to the replayability. You can face-off against your friend, or play co-operatively, one on lead guitar, another on bass guitar. Of course for this, you will need to buy a second guitar. The only problem in the online play is that some games are laggy, and it sometimes becomes hard to join a game. Other than these minor problems and battle mode, Guitar Hero 3 is the best guitar hero game of the entire franchise. With loads of fun, and an awesome soundtrack, you can't go wrong with buying this game.
