There were days when even 20 members were less and people were wanting to be in. And those games had mind blowing setups. I personally love closed setup games more as it really tests you and makes you think. Open setup has no mystery and it gets boring. I remember only in the 2nd game ever over here, Ollie added a serial killer and everyone were lost about how there were 2 deaths at night. That was fun and it kept getting better and better with new roles and all the mysteries, the later games which followed.
