The Marvel Superheros RPG I used to love playing in the 1990s used a Karma system. It was the 1980s "MSHRPG" made by TSR. Very complex and quite good system, honestly, although I'm not a gaming expert by any means: neither video, nor board games, nor #ttrpgs.
If you were a good guy, doing good things would increase your karma. Doing bad things would decrease or even wipe out your karma.
If you were a bad guy, doing bad things would increase your karma.
There were many times that the heroes would attempt to neutralize a foe but go just a little too far, leading to the villain dying. That would zero out the hero's karma, a phenomenon we liked to call the "Karma Toilet." IIRC, one of us would actually play a .wav file of a toilet flushing when it happened, or walk to the nearest bathroom and flush a toilet, or something.
Man, the 90s were fun. I really miss constructive boredom and community.
Black History Month meets RPG meets comics history: fans of the 1984 Marvel Super Heroes basic set doubtless remember the Monica Rambeau Captain Marvel who graced the cover and was one of the core characters in the included adventure “Day of the Octopus”.
This was not out of nowhere: Monica, introduced by Roger Stern in 1982 and rolled into his Avengers run, was a rising star doing the “growing new hero” arc (something Stern excelled at)
