I do have Werewolf, but that's an 8 - 16 player game.
I would like to play Sorry, and Dominoes (Double 9s preferable with 4 players).
I saw a copy of Waterworks at my folks house a while back, but since they remodeled, it could be anywhere. I'll look around there for it if I get a chance, but I believe it has no rulebook, so I hope someone remembers how to play.
