Legacy games are board games whose rules, game elements and story change constantly with each round of play. The decisions that players make while playing have a long-lasting impact and can affect not only the current game, but all subsequent games. For example, players can permanently change game rules, add new elements to the game plan, or modify game components. These changes ensure that each game is unique and evolves differently from the last. Legacy games often tell a story that creates a strong emotional connection between players and the game itself.
