A new game has been invented by a gaming scientist to transport Princesses Celestia and Luna into a large, uninhabited world, with 40 of their most loyal guards and soldiers, to fight each other. The mare who emerges on top will gain nothing but the glory and of course the ability to gloat over the win to their sister! And naturally, everypony not in the game will be watching, and betting on who wins. May the best princess win!
