Everyone talks about Street Fighter or Tekken, but let's hear it for the weirder, unique, underrated, or forgotten fighting games out there.
My favorite is a Gundam game. Federation Vs. Zeon and it's sequel, Gundam vs Zeta Gundam, made by Capcom. The original games in the Gundam Versus franchise of games. imo the series was at it's best when it was handled by Capcom.
I miss Power Stone
Just a weird isometric fighting game that was half Smash Bros and half Street Fighter
Only could play it at my buddy's house because he was the only human soul I knew who bought the Dreamcast
