Yes. All threats to the town. And if you guys are harmless to us, why would we have to kill you? You're not a threat, apparently. So, we lynch a CT then?
The difficulty here is that no one knows the definition of "threat" in this game. In a regular game, the threat to town is mafia. In a multi-ball game, the threat to town is the scum teams/SKs. In this game, givn the wording of the wincons as far as I can guesstimate, doesn't allow anyone to know who they need to get rid of. In those games, scum wincon is "half of town, or nothing can stop that from happening."
My wincon is eliminate all threats to WWs. Monster Hunters say eliminate all threats to "town." Have the CTs claims their wincon?
I think the "fairest" way the BM set-up here could be made is that each group is a group of survivors, and we need to kill off EVERYONE else; that is, so there are ONLY WWs alive, or ONLY MHs alive, or ONLY CTs alive. Because that's how it works with a normal town vs. scum game. "Eliminate all threats to X" in those instances means literally to kill everyone that isn't town. So here, we probably have to kill everyone that isn't WWs/MHs/CTs, depending on who you are.
Of course, the limited number of NKs means this game will last longer than Robz Garden Game, unfortunately. And that is a daunting, depressing idea that makes this game less and less enjoyable.
