Right, I'm just saying. Yoshi's world has always been Mario's world; in contrast to DK and Wario who have their own separate canons.
Anyway, this could be interesting...
I know Sakurai said if they didn't go the "everyone is here" route and started from scratch, Ultimate would've only included a third of the characters it has. I don't think he'd go that far, so I made a hypothetical roster if Smash cut about half its characters. This might've been before Ridley (and everyone after) was revealed, but idk if that changes anything.
Taking another look at it, I don't think they'd even include Peach, but this is just a guess anyway. It doesn't have to be exactly this many characters, but there's 32 here.
