Just had a hilarious experience. I was playing as Gilden...something, the guy that makes lots of money . Anyway, everything was going well, pretty early into the game, I had 3 champs, hadn't encountered any of the other factions yet, and was just building up my city basically. When all of a sudden:
"Faction such and such has been eliminated!"
I never even saw the other faction lol . So I'm not sure why the other factions got wiped out...but something needs to be tweaked here. Maybe the neutral mobs were too strong/aggressive?
Other than that...was a great game! Sad that it ended so prematurely.
