A common saying at wrap up
for an Assassins' guild
game. If you fail to achieve your goals
in the course of the game, you can't say, "Postgame, my character hunts yours down and steals back the amulet of Amon Ra
." There is no postgame.
As applied to strategy games, this is the flip side of the lesson taught by "The enemy's gate is down." What matters is whether or not you won, not whether or not someone else will win the turn after you did.
