I feel in the End, Miyamoto is right, Mario is a old cartoon/comic character, sometimes he owns an entire kingdom, sometimes he has a dinky little house with Luigi, sometimes Luigi has an entire mansion, sometimes he lives with Mario in that dinky house, sometimes Bowser is ruling the Galaxy with a iron fist, other times he’s eating donuts peacefully with Mario and Friends, sometimes Wario is a ultra rich treasure Hunter, sometimes he’s a broke scummy Game Developer, some games like Mario Galaxy 2 pretty much just act like the original doesn’t exist really, sometimes the Moon is smaller then an island, sometimes it’s about as big as our moon
Are these “contradictions” perhaps not, people could (and have) make any amount of explanations for these sudden changes but I think the truth is, Nintendo doesn’t think about it, and the same goes about for any cartoon character
for example, right now Bugs Bunny is going through major changes, one of the profiles being “Space Jam”, is there technically anything that contradicts any other of the cartoons in space jam?, probably not, and there’s some nods here and there but the real reason it’s Seperate is that it’s just, different, Bugs acts differently, the brand is different, the people are different and the power levels are different (Road Runner would’ve cleared that movie hard tbh), and I feel the same can be said for Mario, specially since one of these canon’s is directly a alternate universe inside a book
that’s my honest feeling on Mario Canon, I personally would like it to be connected, but Nintendo just, doesn’t have interest in that idea
