I use the Chisel mod for the blocks of the Castle, you can have a lot of really great bricks with just smooth stone in it, The idea of mossy and cracked stone wasn't in my plans, maybe if it was an old Castle, but my plan is rather a brand new Castle. But will probably have a prison in it and mossy and cracked stone would make sense there... I will probably also use a lot of Spruce wood for details on the Castle...
