I mean, I get that ... Hell my favourite Nintendo series outside of Pokémon is F-Zero. Just imagine how I've felt ... Poor F-Zero.
but, yeah, this is Smash, not a revival of a franchise.
Rhythm Heaven is atleast not dead, it's actually quite active.
Golden Sun however, even more bloody recent than F-Zero (Crazy, right?)
However, Captain Falcon being in Smash and Isaac is not, that way I do get it.
Smash do imortilize the character, and help people shed light to franchises. (Biggest reason I want Lip, to light Panel De Pon games)
But, I don't see why the franchises close to death would be upset by Bayo, other than what I've covered over.
