Well, accctually DTA, it depends on your definition of ''winning a world." TW split into two tribes when it declared, as it was called, "nothing left to prove." It had beaten every tribe pretty much anywhere in the top...Anything...And was done. Many quit, others fought one another for a thrill. In their minds, I'm sure they believed they'd won the world. They declared war on the #1 tribe and destroyed them and their entire alliance.
I'm sure the winner of the Western/Eastern war in this world will feel as if they've won. Or will they? Some may...Some may feel that by not fighting their strongest remaining ally, they haven't won anything. Its for each man (or woman) to determine on his own what their conditions for victory are, and to play for them. That's the point of this game, no?
