No, I mean with Paper Mario in particular...
Like, apparently with Sticker Star, he interfered quite a lot.
For example, he campaigned for having no original characters aside from Kersti, and had the storyline become much less of a focus.
Miyamoto's actually been known to do that quite a lot. Like iirc, he had Rare turn their project, Dinosaur Planet into a Star Fox branded game due to the anthropomorphic animal characters striking a resemblance to Fox and crew. That game ended up becoming Star Fox Adventures
Still love the guy and no doubt is an innovator when it comes to gaming, but he can make some interesting decisions sometimes
