Here's a random thought about the Mario RPG remake that arguably does kinda help Geno's standing...sort of.
It's actually going to be the very first time SMRPG has ever seen a physical release over in Europe. Like yes, it technically was retroactively re-released there through VC and SNES Classic, but simple ROM dumps aside, this is the first time Eurobros have actually gotten this game properly released there.
It's kinda noteworthy in that, since Smash 4, literally every single newcomer introduced has been from a game with a proper physical worldwide release (NA, PAL and Japan). To this day, there are only four characters that were introduced into the series when their original game lacked such:
Ness (Earthbound once again wasn't released in PAL territories until the Wii U VC)
Marth
Lucas
Roy
(fun fact: Marth is the only one whose original game since then did get a true physical worldwide release, through a remake of his first game, Fire Emblem: Shadow Dragon, on DS)
Of course, notice how these were limited to the earlier installments in Smash's life. Also consider how Marth and Roy were supposed to be removed from all non-JP versions of Melee, or how Lucas only got in Brawl because Sakurai was unaware that Mother 3 wasn't being localized.
Might not mean much for Geno in the long run, but it might be something to consider.
