what do you mean usually?
That's the whole point of MM, is for people to create their own roles
I learned a lot from Al's joker game, about how not to make a game, so I have a nice textbook example of a disaster
Regardless, yeah, I think MM is akin to SRM, but I would at least make sure that there is some kind of balance, because if not the mood will be killed quite drastically, as proven by the last one.
