This is a perfect example of what you want to avoid. This person had a disastrous build speed, horrible resource rate, and pretty much no army and recruiting capability. Notice how none of the resource nodes are not deleted. This is a huge indication that this player was a noob. Most of the castles you will capture will likely be something like this. Once and a while you can get lucky with a nice capture. Oh this was a lawless BTW 5k points, notice no castle.
Military City specializing in Knights
This city is a military city specializing in knights. Notice it is still under construction because only some of the cottages have been deconstructed. The city is at the stage where cottages are slowly being converted into additional barracks/stables. It is completely reliant on a feeder city or trading for resources and additional food.
