Kind of assuming they go the Mario Kart 8 Deluxe and just port an upgraded version of Smash 4 to the Switch instead of building a new game from scratch, what kind of features would you like to see added?
1. Since the Switch is both a home and portable console, I would hope it would have all the stages/features from both the Wii U and 3DS versions of the game.
2. I'd like to see the boss fights from Brawl get brought back. I don't expect to see Subspace Emisary return, but it would be cool if they added a mini-boss round to the middle of Classic mode. Bring back Petey, Porky, Reyquaza and Ridley from Brawl. Dark Emperor, Yellow Devil and Metal Face from 4. And then throw in some new ones. Giga Dry Bowser, OoT Ganon, Mother Brain, Whispy Woods, Medusa, etc.
3. New characters are a must. Fully expecting to see Decidueye, Inkings and an ARMS character playable. Hoping for Simon Belmont. Also hoping Ice Climbers, Snake and Wolf return.
4. King Hippo and Eggplant Wizard assist trophies. Captain N costume for the Mii Gunner.
