My main reason...

The reason I was on the Nintendo eshop long enough to find and download Legend Of Zelda Minish Cap,was cause I heard about new stages and outfits for Super Smash Bros. Wii U and 3DS. I wasn't really interested in the outfits, but I really liked the stages. In addition, the stages are mostly classic Smash Bros. stages (with one based on Mario Maker). I think these stages are cool, how about you?
