I'm just wondering if this has ever been considered as a possibility, but I feel like it would improve the dynamics of a cult/cthulu game if cthulu was also the cult leader.
One: it would give members of the town incentive to try to find and out cthulu (in sandbox games, at least, this is often seen as a scum move since if mafia doesn't know cthulu, they're more likely to kill cthulu and thus reveal themselve in the process). It would also make identifying the leader of a cult easier, as opposed to every other member.
Two: it would remove the possibility where cthulu gets culted, making everybody question their life choices.
Three: it would remove the ambiguity of a cthulu win. He already wins with cult, but it doesn't feel substantial because he doesn't get his own message.
I don't know, I'm probably missing some major factor of why this is a terrible idea, but I'm kind of digging the thought at the moment.
