I was pleased to see Marvel Super Heroes while we were at the Carolina Arcade Museum in Forest City, NC. My brother and I had the game on PS1 but I don't think I had played the original arcade version.
Though it's not much different from the PS1 port. I still recall my brother using Iron Man and his proton cannon.
But you fight as most of the Avengers and some of the bad people too. The series later morphed into the Marvel Vs. Capcom games.
Even Thanos appears (as a boss) but I never got that far that day. I just played against Daisy and I destroyed her fighter.
