Impressive at first, but it's over much too quickly.
The story is about a young boy and his furry friend Daxter on a quest to save the world. Daxter is sort of like a mini-Crash Bandicoot, only much more annoying. He doesn't shut up. He's not funny in the least bit. Jak is completly silent. He's pretty cool, though.
The graphics are very good, very detailed. The music is forgetable, Daxter is more annoying than funny, but the worst thing about the game is the length. I mean, I start up the game turn it off, and come back to play a while later. I check the percent, and I'm already like, 15% done!
In short, rent it, don't buy it. It simply isn't worth your hard earned money.
