Ah, I remember this one like it was yesterday. It was my very first attempt at building a city. The city came fully equipped with libraries, apartment houses, villager housing, gardens, armories, mansions, and an evil fascist dictatorship. I would show you a better picture, but the save file is long gone.
This was a fortress I built for a paladin lord. I was really proud of it until I learned that quartz has all the blast resistance of wet tissue paper.
Now this is a fortress! It delves deep into the mountain, and is protected by an army of soldiers. That white shrine beside it is dedicated to Celestia, by the way. No, that tree isn't sprouting out of thin air, thanks to my poor photography skills it just looks that way.
A fortress-city I recently built. This one is fairly big; most of it isn't pictured here. It has an extensive sewer system running under it, for no reason other than I was bored.
I think I'll let this one speak for it's self.
