If you want people to read books, it works best if you get them to agree that there is something in the books that they don't know, but that they would like to find out. Then people will happily work hard at reading the books to learn something. If they thought that they knew everything, they wouldn't bother to read books. The maker of a game might or might not admit the lies that the game is based on. If she keeps the lies a secret, the game might become aberrative.
People love playing games.
The fun and learning achieved from playing can motivate them to deliver their utmost performance and work hard for the game. They usually don't mind much that they are being tricked a little bit into playing the game. Often games designed by others can be most fun because you can't quite see through all the mechanics of the game. That can allow you to just experience and enjoy the game without a danger of accidentally undoing it because you know too much about it. If you design a game for others to play, make sure that you don't make the real purpose of the game the stated goal.
