So I read a review for the 3DS eShop version of Cave Story and I was wondering which version to get. It sounds like the eShop version has more content and the retail version was a remake of the original with 3D models, but I'm hard pressed to actually find any solid confirmation the differences between the two. Can someone help me decide, please? EDIT: Yikes! Is the retail version out of itself everywhere? All the used copies are £40+.
