Yeah. I don't think 1e is underrated, but I do think it's over-hated. It's the system I largely got started with for TTRPGs. It's really not that difficult, but it does let you make things very complex.

I know why people went for D&D 5e over Pathfinder, but I think it should have been seen as an entry point, not the place you stay forever like it's become for most people. It's dumbed down, but also with you having to remember a lot of exceptions and things because they dumbed it down too much and tried adding things that didn't fit exactly into the rules.
