Mario 64 is still a very recommendable 3D platformer (a genre that sees only a handful releases every year) that aged really well; Starfox 64 was just released again with better graphics because the game’s still good (in a genre that’s basically dead); OoT and MM are still peak Zelda in a very rather small pool of Zelda-likes (not action RPGs). So yes, I don’t see much development in any of these areas.
