If there is only one wolf in each pack then the number of packs would have to be insane. I have no idea what an appropriate number is for such a scenario but certainly 5 or 6 wolf packs is not impossible.
I'm not sure how or even if that would work though. Vote analysis is the number one tool us villagers have to figure out who the bad people in the informed minority are. If wolf packs consist of one person each then there is no such thing as an attempt to save a packmate since there are no packmates to save.. nor is there an informed minority.
Also, if all the wolf packs know who all the other wolves are wouldn't one of them just out the rest to get all of the competition lynched? Or would you get some kind of cold war type standoff where each individual could decide to launch the nukes but would not because of the risk of mutual extermination?
In such a scenario the village has an advantage I think - it gets to stand on the sidelines while all the wolves duke it out amongst each other ;-)
(It'd be a tad bewildering though ..)
Id say that there are 3 packs x 2 members.. To have multi packs with only 1 member would be pretty boring for the guys that hunt last. If that theory was correct, then 4 differant packs with 1 member would be max id say. Plus, how on earth do they reach plarity with the cave dwellers to win if only 1 member??
