smash run is pretty much the only thing beside normal matches and random minigames (not fun ones like warioware) thats in the 3ds version
that being said, its pretty neat. too bad its not internet compatible.
doesnt the wii u version have everything in the ds version plus 8 player and a level editor?
EDIT: oh, it got replaced with smash tour :-/ oh well, hopefully that isnt such a Bored game *badum tss*
Smash Run is pretty fun. I just wish you were able to interact with other players going through the same area as you, instead of going through completely separate maps.
