### A world-building game for any number of players *This is How it Happened* creates a setting with a rich history that all of the players are invested in. The resulting setting can be used as the seed of another role-playing game. Players take turns: step one always comes first, and step two always comes after that. After step two you start with step one again. ## 1. One thing happens. The player says one thing that happened, ideally in a single sentence. You can enforce the strictness of the one-sentence limit as tightly or as loosely as you wish. ## 2. Some time passes. The next player decides what unit of time has passed. The player should say whether an hour, a day, a week, a month, a season, a year, a decade, or a century has gone by. ## That's it. Add wrinkles or random chance to the game: 1. Roll 1d8 to determine which increment of time has passed in step two. 2. Draw a tarot card and explain how it fits in step one. 3. Roll on any random table in an RPG sourcebook. 4. Let a child take a turn. 5. Try something else!
