[gcbqerem] Ender's Game

Create a game, perhaps a first-person shooter, in which genocide is the only way to win.  However, the game creator's task is to make it extremely unobvious that that is the optimal strategy (despite trolls who will no doubt try it), perhaps a surprise ending that can only be discovered after significant game play.

The inspiration is the radical and highly politically incorrect hypothesis that, in many of the historical and even current genocides, the combatants are acting rationally.
