im going to try and compile a list of roguelikes where lycanthropy(werewolf disease)
occurs, and im also going to comment on it if i have played a werewolf in that game
nethack/nethack variants(very rare in my experience,possible start race for SLASH'EM, lycanthropy is a MAJOR drawback with no benifits worth mentioning)
iter van ad necem(not too rare, not annoyingly common, well balanced)
ragnarock/valhalla(ive had the "lycanthropy" intristic, didnt seem to do anything, anyone able to shed some light there)
anyone got anything else?
