That sounds smart too. I'm just wondering if Nintendo is truly done with those franchises as far as innovation goes. Miyamoto is talking about rebooting Mario. I really feel and hope that Nintendo is looking at all of their franchises and asking themselves where they can innovate, no matter how drastic. But that process needs time and people really want MK and Smash for Switch, the Wii U versions are basically perfect so they're fine with some enhancements. They'll come out in the first 12 months and that's great. But for the next MK and Smash there needs to be some real, palatable innovation. Otherwise there is no need for them to exist.
And I think they will exist and they will exist on Switch.
I just can't envision where those two franchises can expand to that would justify a new release. I mean we already saw the additional 200cc mode being added to Kart a year after release. Any innovations like a new-and-improved battle mode or mission mode could be ready for Mario Kart Switch, or release down the road without justifying a new release in the franchise. Why would they go against their one-per-console strategy? It's worked for decades.
I don't think those two franchises need fundamental innovations as you suggest, atleast not to the base gameplay. More online options, more abilities to spectate and share, deeper character/kart/level customization, etc. How about making custom Grand Prix's in Mario Kart, where we select the courses, item stats, and individual AI skillsets, and share online for comprehensive stat tracking? Same goes for Smash with customized classic-modes? How about finally adding a goddamn tag-team mode in Smash Bros? There are tons and tons of ways these franchises can be expanded without affecting the perfected base gameplay mechanics.
All I'm saying is these two franchises have a lot of areas to expand and improve outside of the base gameplay, and I simply can't imagine what would justify a new release until we have a tech leap or VR or something.
...and if they really wanted to innovate the base gameplay of Mario Kart, make a new Diddy Kong Racing. Or a new fighting game to compliment Smash bros. Both of these games are so deep within the collective gamer mindshare and competitive community I would almost urge them against innovating too much on the base gameplay.
