Actually, this could be a hoot if done right in a quest-based 4X/RPG.
At game-world creation time, your IsCheater flag is initialized to true.
Your mission, should it matter to you, is to find the loophole in the game engine during your play, discover where your own flag is stored (it's physically on the map somewhere!!), and -- change it to false.
O Henry Punch Line: The only way to do this is -- to cheat
