The Village of Hommlet has been one of my all-time fave TSR adventure modules since it came out, and is one of the few I still own in physical form. The varied NPCs, the numerous side-quest hooks, and the primary adventure are amongst the best TSR had to offer. While I have long-since ceased to be a fan of D&D (past AD&D 1e), I'd gladly run Hommlet for Ba5ic, Cairn, or Knave (with requisite adjustments).
