I don't want "action" movie fantasy, no. If I did, I would just be happy playing D&D.
AD&D had rules for regularly checking to see if your character picked up a disease or became ill, for instance. 5E lacks that, among many other things. However, even some of the systems it has are overly simplified for my tastes. Instead of continuing to mod the heck out of it, I was curious what other systems are out there for medieval fantasy that more accurately model real-life in many of the terms I've expressed.
I would rather play a game where "hits" are actual hits and you might survive a few hits before you died, but one hit might also kill you. Combat should be avoided whenever possible, and a man with a drawn sword is actually dangerous.
