Cave Story is without a doubt one of the best games I've played in the last 2-3 years. That site is really helpful if you're on a 2nd play through and trying to get some of the secrets (messing a few things up the first time actually improved my opinion of the game dramatically). The port on the Wii is really nice. $10 is about as much as a controller for a computer, and the game is superior when played with an actual controller. So you might as well get the Wii version with the extra goodies. If you do play the Wii version, I suggest classic sound and updated graphics. The remixed soundtrack just isn't comparable to the original (because it is awesome) and some of the sound effects get INCREDIBLY annoying in the update.
