"werewolves are known to be..."?
how many werewolves do you know IRL?
alpha wolves are monogamous, there is one male and one female to rule a whole pack. ende.
everythying else is stretching, even in such fantasy genre.
btw, it doesnt amtter if this is a fantasy game or not, some things just dont fit in there- or they do fit but make game worse than it could be...harem, or better to say "pokemon-catch-em-all" (as any proper haremer knows, harem isnt a harem if one cant get all chicks, including dead ones too), is one of those things.
btw, did you try to come to any other "proper harem" game, grandma house or wvm, for example, and to say "man, this is some shit, wtf is happening there - any chick is just jumping straight on mcs dick and is perfectly happy to share him. thats not avn/non-fantasy, no way hose? im sure, if not done already, you are planning on dosing so, right?
