Is this the correct forum for Blood On The Clocktower questions? It's more of a social deduction game, and less of a RPG.
Blood on the Clocktower is a classic diceless freeform large-group roleplaying game. The game instructs you to take on the roles (see: roleplaying) of a bunch of villagers in a gothically named village. There's a GM. You're meant to act in character, although it avoids saying to what degree.
This is entirely different to a board game where you don't do any roleplaying. While there are likely versions of this game where no roleplaying occurs and it's just mechanical interaction/questions/guessing, just like how in D&D you can have a dungeon crawl with absolutely zero roleplaying or IC interaction and just 'I roll to attack' 'pass the chips' etc, the rules clearly indicate roleplaying is meant to occur (just as they do in D&D), there is a setting, there is a GM, etc. Couldn't be more clearly on topic for this stack.
