Game designer Rob Daviau claims to have come up with the idea at a work meeting after jokingly asking why the murderous characters in Clue are always invited back to dinner.
[12] He compared his legacy games to that of a concert where you "buy a ticket for an experience"[13] while Haoran Un of Kotaku describes the idea as "avant-garde performance art".
[2] For instance players might be instructed to write names on cards, place stickers on the game board, or destroy some components.
[11] This causes each copy of the game to be unique at the end[3] and has earned the legacy genre criticism in that there is a finite amount of replayability.
[7][13] Some games have been designed to be replayable with refill packs or non-permanent stickers while others are still playable with the final permanent changes once the campaign is over.
