And going back to the biggest example of "fans" getting to work on the official thing, Taxman and company didn't just get tapped out of the blue to work on Sonic Mania. It took looking at an actual pitch showing off an engine to convince them that there was something worth devleoping there and then getting saddled with just porting over existing games to a new modern engine until they were able to build up a relationship enough to where Sega allowed for them to work on new content in Sonic 2, and then again to where Sega was willing to let them make a "new" major commercial game.
If the company that people keep parading around as the example of "how to handle fan games" works relatively slowly like that, why the hell would anybody expect Nintendo to be even more generous and just suddenly give DoctorM64 the reigns to the Metroid series when he has significantly less to offer them than what Taxman had when he and Sega began their professional relationship? Even under the best conditions, a similar relationship would start with Nintendo working with DoctorM64 to use his experience to make modern ports of Super Metroid and/or GBA games that don't rely on emulation. And that's kinda bungled by how AM2R is built on gamemaker
It sounds like its Taxman's modern day engine that impressed Sega and got him the job.
