Legacy games are board games that change over time based on the outcome of each game played and the choices players make. They will make physical changes to the board game by marking the cards, placing stickers over the board, destroying components, opening sealed packages included in the game, and so on. The changes made in a Legacy game are permanent; what is done cannot be undone. A Legacy game's full experience is played out in a campaign that can only be played once. To play the campaign again, the players would need to purchase another copy of the game.
