AD&D detailed rules?
My group abandoned AD&D in 1984 due to it's inconsistency in detailed rules. Went with GURPS by Steve Jackson Games, and have been playing consistently with comprehensive DETAILED rules that -even with some problems- are hardly ever inconsistent between the various books and scenarios. Last Saturday, 11 March 2017, we again played in my campaign world -a YURTH variant based on the FREE starter adventure, Caravan to En Arris. And yes, we're still playing 3ed revised 33years later.
