It's better then I thought it would be.

When I heard about a game where you have to press five buttons in order to simulate a rock song, i thought it would be stupid. When I discovered those five buttons were R1, R2, L1, L2 and X, I got even more frustrated. I figured the game was only worth playing if you had the guitar. The guitar is expensive, so it wouldn't be worth buying it for a couple of games.
But a friend of mine played the game at someone's house and asked me to buy it. (he doesn't have the play2). He said he'd pay for it, so I fugured "what the hell".
I bought it and played it and found out it was increadibly fun. Not a "must buy" game, but a good enough entertainment. It's good to play when you're stressed, in order to clear up your mind.
