Oh, I thought a keep had 500 more lockdowns than an 18x18. I also forgot about the increased storage code. What would that give - 20% more on top of the increase that comes with having ML?
*EDIT*
I just double checked on the Homes and Castles forums. A keep has a storage limit of 2626. An 18x18 has 2119.
When forced to choose, I actually prefer the layout of a keep over that of a castle. Can an increased storage code be used on a keep?
