I recently was thinking this, began rereading the PHB to check the rules for reals. Everything is dope until you get to the meat of it, past the equipment section. The combat rules are pretty awful.AD&D 2nd Edition forever!
I like lots of things like saving throws being a wacky chart based on class and level rather than ability scores, etc. But it's a rough ruleset once you go deep.
