From the introduction:
This game is designed as family fun in the spirit of classic fantasy roleplaying games, where the players take the role of a band of heroes venturing into dark caverns in search of mystery, riches, and danger. I’ve loved those games for thirty years, and I do have a soft spot for them, but as a family, we don’t have the time or patience for the complexity of traditional roleplaying games. This game is the result.
What’s different about this game? You can get a Dungeonteller game started in five minutes, without lots of dice-rolling and writing down numbers. Choose a game master, pick a character, and let the adventure begin.
