I conquered a County last week and got us 1 fortress, I see that someone did it again recently.. Who?
Also, I noticed that a county takes up a town space but you dont need to have a town spot open to get one. I made the mistake of conquering a county before I maxed out in cities. I am going to make duke before I conquer another one. I combined Nastyal's army and my own. This weekend, we are going to combine are much larger armies to conquer a second one. We'll keep you updated on how it goes.
Wall defenses are not a Joke, stack up on battering rams, balistas and catapults. Also reepers and such. I did it with only 5k reapers and such, but I had to revive myself because the wall defenses killed me after I killed all the monsters... over 200k butchers.
