Well... I was playing M.U.G.E.N, and something occurred to me - a traditional 2.5d fighting game, kinda like Street Fighter, KoF, or Mortal Kombat, but for Smash. I mean, you'd be able to reference a lot more source material with command inputs and such, such as Link, Simon, Cloud, Joker, and Bayonetta having more of their items, magic, moves and other such things. (After all, Cloud and Joker massively lose a lot of their magical abilities, Link and Simon have a lot of other items and such, and Bayonetta is from a Platinum game.) Furthermore, I'd love to see it in a sort of psudeo-anime style - kind of like the FighterZ artstyle - as I personally think it would suit the style and such of Smash as a whole. (For an example, check out that animated Link vs Pit video, it's gorgeous.) However, still having the 'classic' Smash alongside that would be good as well - more as a party game, and then the 'fighting game' can be this new one (where Nintendo would hopefully focus more on online play and such I CAN DREAM OKAY)
