Um...Jammer Lammy? Ok!
The gameplay plays like this, the teacher plays a few notes, you repeat them on your guitar, or start your own riff. It's really fun to play the guitar, by the way. You play to different kinds of rock, like metal, pop, punk, and others.
The graphics aren't really that great. The style of the graphics is okay, but not outstanding. It doesn't really work well in cutscenes, as the people are flat, so when they run it looks more like they're wiggling.
The music is great! The sound is pretty cool, playing the guitar is soooo sweet when it sounds like this. You can even use different effects on the guitar to make it sound the way YOU want it to. That's right. You can make a pop song sound metal. Seriously.
The game gets old after you've beaten it once. It does. All of the other modes feel like bonuses. You can beat it with Parappa, but that's the only real thing to do after you've beaten it. The A.I. can be frustrating. When playing a versus mode, they sometimes get points for no reason. Like, when I was playing Parappa, he was doing really crappy, until he said something really dumb, like: Then pouring comes rain out of, and he won.
Other than that though, it's great. You can buy it really cheap now, so I recommend you do so! Because if you don't, you'll be thinking, like, why didn't I buy it? I wonder if it really WAS that good? And it'll bother you until your really old and stuff! Huzzah.
