Cave Story, an indie PC game released over six years ago, is still winning new fans today following subsequent releases on the Wii and DS. Now it's being remade, in 3D, for Nintendo's newest handheld.
Cave Story 3D is a complete remake of the original platformer, with every character and every level transformed from its humble 2D, pixellated origins into "2.5D", which is a two-dimensional game giving the illusion of three dimensional space.
Personally, I think a lot of the charm of the game came from the 2D graphics and changing it seems like more of a cash in. The creator of the game seems behind it though, so I guess it's what he wants.
Here's two screens showing the before and the proposed after:
On a final note, is there any games you think are a classic and should not be remade?
