I remember watching a Mario timeline a couple years ago, when it came out, that was amazing (and 5 hours…) but it’s fairly outdated now and there’s some things I disagree with (eg their criteria for including other franchises was very strict, only including games distributed by Nintendo or had the crossover on a Nintendo console - the latter of which only including the one game, not the whole franchise) so I’d shuffle a few things they did, as well as add other games I think should be included that they didn’t and add the newer games.
I’d probably include the prologue narratives in the instruction manuals that Nintendo made for their games, too, as well as any other forms of media that I could fit, that wasn’t included (eg Rabbids Invasion, not just the Rabbid games - yes, Rabbids is part of the Mario universe)
