I think it's really rude to act like a host can just get 12~13 players if they just try to. We don't have the signups BECAUSE those people -don't want to (or can't) play-. Most of the last several games had multiple people from elsewhere too padding the numbers iirc? (And not everyone actually knows many people from other places to ask)
Also if a host can manage to fill a large setup I don't see why they shouldn't be allowed to do so.
Like, really, it's easy to say this, but unless you're dragging 5 players in from somewhere other than MotK it's obviously not going to happen right now, and it's rude to keep saying "well someone OTHER than nnr could totally get that many signups instead :3", esp. when it isn't a realistic statement. (Yes, made slightly ruder, but that's what's heavily implied whether intended or not, and it's necessary to get this point across)
But anyway, the bottom line here is, we clearly don't have enough people with the time/interest for mafia to realistically fill up more than 9p setups at the moment, so there's not much point in trying to host bigger games; it'll just stall in signups for months on end. Even the last game with several out-of-motk players took almost 2 months and there had been pressure at the end for someone to just sign up before people have to start dropping out. NNR should totally stay top of the queue for future signups assuming no complications (although tbh, the fact that he jumped queue is already a minor complication in terms of "um should he stay there after his game doesn't actually go next??" but unless any of the other hosts really care) but either a filler game or someone else's game should go first as 9p (or his gets adapted to it if he decides on that, whatever happens) in the interest of mafia actually happening; we'd most likely be able to play at least one game before these signups finished in any case.
edit:Unless something happens like refa saying yes, etc, and NNR is actually looking at being 1 player away soon. 3 signups away is highly liable of being forever, unfortunately
