I think larger setups would be harder to fill, so you could make a X dependent on the size of the game. Other than that, I think slow signups indicate low interest which will doom a game anyways generally. This could be one of those fancy saturday/friday/monday whatever day of the week it was chats. 
but that’s unlikely, since you don’t like the idea
Also some setups can be scaled down and be run with lower player number if they reach deadline as a possible out for large games.
I think Solic’s idea of having a ‘games get x days to fill’ sort of cut-off could be good because it ?might? make people less likely to join games they don’t want to play just to make them fill (which has historically led to reductions in game quality)
Does anyone here know Warrior Cats and is excited for the possibility of this game running? Just a note to DatBird (or whoever will manage the queue at that point): This game cannot run until the summer, and will have to wait until the summer after next summer if the game cannot run next summer.
I know of Warrior Cats, never read the series myself but it seems cool and I like new ideas for games
