You'd be surprised about how some old games differed between versions. Adventures of Batman and Robin, TMNT: Tournament Fighters, Batman and Batman Returns (a lot of Batman games, really) were all different depending on which version you played.

For Captain America and the Avengers, the arcade version was the original, while the home ports featured some differences, especially the NES version, which had different enemies.
