Continuing off my post a while ago about the NES, Genesis, and PS1 having very distinct early eras, I think they each have a few games each that can be considered where the early eras end because of how influential they were for it's future games: Super Mario Bros and Ghosts n Goblins for the NES, Sonic for the Genesis, and Resident Evil, Tomb Raider and FF7 for the PS1.
(Also, he was in Kingdom Hearts 2 and you fight him a couple times early in the game. There's a part where you fight a bunch of clones of him, so I guess I get why some people might think Black Mages in general are Vivi.)
