I am 100% positive. There is only 1 victor of a world. You even get a certificate that says WINNER on it. Then everyone in the alliance gets each of their names put in the Hall of Fame. Victor of the World is the one that matters.
The shiny crown on the profile is meaning less, you can have mine. More than 1 alliance can get one on each server, so it is a watered down version of everyone can be a winner award.
No matter what your leaders tell you, Sin.dicate won the server!!! I offered a chance to let them get a crown, they decided against it. 25 more days, and it is over.
