This guy... I still didn't get how the hell did he he beat me. I'm sure that i've done some mistakes, but he doesn't explore the map at all, stay defensive for most of the game, make more dwarfs than villagers...
Also he didn't make jarls, nor huskarls... I'm pretty comfused
When i saw the walls, i was sure that i won. I thought that if he walls himself he will run our of gold, and since i control it he will lose.
Probably my main mistake was not booming after seing the walls to make jarls and hill forts and defend the gold better.
