There are lots of great games that are available for free (or at least just the cost of printer paper and ink). Some are homebrew, some are games that are available to print as a demo, and some are just weird. And I cannot stress just how much Jondi hates Werewolf.
There are just some games that only really work with larger crowds at parties. Some of them we never want to play ever again. Jared defines a party game as one with few rules, lots of laughs, and many players. Jondi defines a party game as one she can play while drinking.
