Beautiful game, the illustrations look like Japanese brushwork
This is probably the only game that was made for the Wii that I ever enjoyed. I would get the PS3 version now that I have one, but I don't know, in this case, which one I'd recommend. I think it would depend on the person--namely, for the Wii, much of the gameplay is drawing artistic shapes on the screen as your attacks, such as cutting enemies in half, and this was very awkward and difficult for me as both a hater of Wii motes and gross motor skills. However, many people find this experience very satisfying and fun, and are willing to put up with the Wii's far inferior graphic quality for it. So...I guess it depends on whether your willing to sacrifice quality for a controller that lets you imagine you are actually painting. Just be sure to keep in mind the shortcomings of the Wii mote, and the way the sensor tends to act of, ignore, or completely misinterpret your motions.
But on to the game. This game is incredibly. I haven't finished it yet; college applications tend to suck the time out of the day; but its a great game. The adventure is superb, it has touches of maturity but nothing strong enough to turn parents off, and the violence is really cartoon violence with painted creatures and other such things. There's hardly any blood, but the animation is gorgeous and artful.
