i have to agree the whole concept doesn't make sense how do you define a game especially when it has no players the first sentence defines a zero player game as a game without any human players no citation the second sentence defines it as a game played by artificial intelligence whether the player is human or machine there's still at least one player and if the game of life has no players is it really a game or is it an algorithm or mathematical thing if you grow a flower or a crystal its not a game so when you grow the game of life is it really a game or if one considers the programmer user as the player since they will be the one to pick initial board then it's not really a zero player game
