As a zoomer I don’t know which ones you’re referring to. Returns did what you guys are saying should be done - Supes is invincible and nothing can hurt him, it’s the city he has to worry about, only the bosses can hurt him and that’s where he gets a health bar - and players did not respond very positively to that at all, game is regarded as boring. Turning the entire game into one big escort mission does not make for a fun experience. When you’re adapting something to another medium, changes have to be made. Batman does not heal in the comics from executing perfect combos but he does in the Arkham games because it would not be fun to have to go back to the manor and have Alfred heal your wounds after every fight.
While it might not be “comic accurate”, I expect if a Superman game ever were to happen there would be arbitrary limitations to make the character work for a game. I don’t believe that players would reject a health bar the way you think, previous Superman games failed for reasons regarding budget rather than because he had a health bar. People certainly seemed interested in the Factor 5 game which would have given him a health bar and nerfed him to DCAU levels. If you are correct that people won’t accept such changes then the people who say it’s impossible to make a good Superman game are right. You could make a decent tech demo of Superman flying around putting out fires and saving people which would capture the “Superman experience” but it would not be fun and it would never be commercially viable.
