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
