Pros: One of the most beautiful games out there, with a really daring an innovative art style - the game is completely rendered as a moving sumi-e painting. Great storyline, fantastic gameplay, hours and hours of fun. Totally worth it (and then some).
I love this game. I've beaten it several times, but there is always something I haven't seen or done. They encourage you to replay it. I preferred gameplay on the PS2 to the Wii controls. Cons: After a while, the story gets a little weird. However, the graphics and the overall game are too good for it to matter.
