@Mr_NutterButter literally all they have to do is make new cool levels and progress a story forward in a compelling way with some sweet set pieces. they could honestly delegate it to more of a AA endeavor. not everything has to be so massive. in fact that's partially why the game industry is failing. nintendo plays it really safe so they aren't going anywhere, but that's also part of the nintendo problem.

i honestly don't think that nintendo is dumb enough to the point where they can't think of new ideas to incorporate into f-zero and star fox. i think they want to make things that are much grander and require a bigger budget, but f-zero and star fox are a bit more niche franchises so they're worried about their profit margins or whatever.

f-zero could incorporate flight or transforming vehicles, but maybe they think that's too close to mario kart. who gives a fuck if it's fun though? now nintendo has kind of missed their opportunity at this point and 3 other games have come out that incorporate a bunch of stuff they could have with f-zero a long time ago. fast rmx has color shifting. aero gpx has flight. xf extreme formula has alternate vehicle types and a super unique boost system that prioritizes speed.

star fox doesn't have to be anything crazy in the gameplay department. it's totally okay for a game to remain samey as long as it's good. there is a reason why everyone continues to sing the praises of star fox 64 nearly 30 years later. it's peak star fox, and nintendo knows that which is why they keep chasing it, but unfortunately they aren't chasing the gameplay... just the story beats.
