This is the worst made up statistic ever.
Here's a more realistic outlook:
75% of players just want to play the game as a knight or a lord and fight other realms. 25% of the players care about progressing and being power hungry. 90% of those 25% just want to keep the power and not do anything for the fun of the other 75% once they get it. Its the 5% of the 25% that will make things more fun.
THE 1%!!!!!!
They've been called job-creators and fat cats... but now we know... they're FUN-CREATORS!
