SF2 deserved to hold the title for a long time. It basically created the fighting genre.
But here's the thing. I was never much of a fan of fighting games back in the 90's even though I loved going to the arcades. Street Fighter (or Mortal Kombat) just never did it for me. I did like the various Capcom Marvel games, but not nearly to the extent of Smash Bros. Smash Bros. just feels right. I never really thought I liked the competitive aspect of fighting games until Smash Bros. I just needed to find the right game.
Now, SSBU really takes the franchise to the next level. There are so many frikken characters and they keep making more. The new champ deserves the title.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
