I enjoyed it alot at first, got bored with it about a week later, then right when I was about to give up I met some cool people to hang out with in the game. So IMO unless you can get into the "social" aspect of the game there isn't much there.
I'm hearing there are some motion-control issues with Okami, which is a major league bummer. It seems that this seems to plague any third-party Wii game. But either way, the public view looks to be favorable and I'll be getting Okami for the Wii.
