I never played it myself, but I've seen a few reviews of it....
There's about a 50-50 split between people saying it's really good or downright awful, so honestly, I have no idea. It always looked good for a Wii game, and the bits of the story I’ve seen in the reviews seemed kind of interesting, as far as I remember.
It’s really just a question of whether you want a story. I mean, just grab it and try it... at worst it’ll be bad, and you can trash it and have wasted nothing but a bit of time. At best, you might love the story it tells, and it is a good game.
