You know how in movies, cartoons or TV shows you'll sometimes see characters playing some sort of made up tabletop game, usually one that is a reference to, if not an outright parody of, an existing game like Magic the Gathering or Dungeons & Dragons or the like. Well, it turns out a bunch of those games actually make it into real life. Sometimes they are homemade versions where fans deduce or make up their own rules for a game and sometimes they are an actual product published by a respectable gaming company.
If you know of any such games that can be bought or whose rules can be found on the web, post them here. I'd love to know just what can be found on this glorious thing we call the internet... If not for any other reason then because from the first moment I saw them on that episode of Parks and Recreation I've wanted to play Cones of Dunshire soooo bad
