But would people enjoy another system more? Do people only enjoy DnD because it's the first reasonable system in the genre they tried and don't know how much better it gets?
The grognards aren’t going to like it no matter what but I’m not sure how much this really matters for everyone else once you get to the point that human story telling, lore, etc. is doing most of the things which a player really cares about. Most people I know have generally been moving towards fewer die rolls because everyone thinks it’s about the story, not the simulation. When I think of the other systems I’ve heard people play the appeal was something like a different setting, not fine tweaks on how you handle combat.
cRPGs are interesting because you get less of that color but have the capacity to actually do all kinds of calculations - get rid of a single HP value and track body parts individually, process damage based on location, use complex non-linear calculations, all are orders of magnitude less work than the video effects will run. I think we’ll see more divergence there between what humans enjoy running versus playing if they don’t have to do the math.
