Cave Story Wii ver. has many extra feature which I think is worth buying it and supporting the company
it has the remake(Wii) and original graphic(Pc). also has the remake of the music, which imo I say its one of the best game music i ever heard. Boss rush, a Sanctuary time attack mode. And my fav. which you get to play through the game as Curly Brace. Cave Story is one of my Fav. game, even though I have already beat the game, I still come back to play some moar, for those who have a Wii, you will totally love Cave Story for the WiiWare. Go buy it!
