Level Up & OSR Enthusiast
I was always bigger on homebrew based on the rulebooks over modules, so that makes sense. Even today, modules often don't match with expected play as expressed in the rulebooks.I think there was also a disconnect between the old-school rulebooks and the old-school modules.
Reading the rulebooks, you could easily get the impression that magic was rare and wondrous. They tried to convey that big magic and "high level" were not something encountered everyday.
But then you get the modules, where the amount of treasure presented could charitably be called excessive (and not just in the dungeons). And where mid high level NPCs popped up all the time.
