Except they don’t? What about Odyssey was new? It’s just a new version of SM64. Sure, it’s got a few different mechanics than SM64, Sunshine, and Galaxy, but those are all the same game at the core, right? This isn’t the only series they do like this.
The game mechanics and gimmicks are different in everyone of the games you just listed.
Barely. Odyssey even specifically references most of the older games to point out how it’s very similar. They all add a small movement mechanic, but other than that jumping has been the same since SM64.
If we say the Mario games are totally different and don’t reuse ideas, no game does. Literally every game changes at least something small. Hell, patches in some games change more than what has changed between those games.
