Besides Werewolves what do you think the Gamepack will have in addition?

I don't think the OP is suggesting that werewolf shouldn't be the core feature, just simply speculating on what else may be included.
Occult play is a bit of a niche market. Creating a pack that only appeals to such a specific group wouldn't make good business sense. Yes of course the core gameplay will center around werewolves... but what will the buying motive be for those non occult playing consumers?

Hopefully a nice new world, an interesting cas addition... maybe a romance system? One can hope, and speculate.
