How come I'm always the BBEG?!?
I'm a good villager too! And we basically BROKE Hogwarts for the Teachers (masons) in that one. See? I can break games for the good guys too!

In all honesty, I'd say DON'T give roles to everyone. Games like that tend to get broken of their own accord with litle or no help from players.

But it looks like fun so far!
