I picked up Okami for the Wii earlier this week. I've gotten through about the first hour (past the tutorial and the first combat), and I like it. The paintbrush action is great fun, and quite easy for me with the Wii-mote, and Amaterasu (the wolf) is a heck of a lot easier for me to drive than Indy (yes, I'm still trying to get the hang of the Lego game).
The art is gorgeous, and I'm really getting into the story (of course, the fact that it's based on Japanese myth helps, too).
