What if the Marty of the Happy 1985 goes back in time and resets every to the version of 1985 that our main Marty experienced. And it is a loop that goes on forever with one Marty making the happy version and the other always making the sad version.

I always assumed this was already a trilogy with the Age of Calamity Hyrule Warriors game existing as a semi prequel to the series and ending with TOTK.

It was such a good game. Different timeline, different style, but awesome nonetheless with the same characters, art style and game map with altered stage layout. It would have been cool to travel on foot between each fight, and walk through the villages prior to how they ended up in BOTW, but that's a minor gripe.
