Yes, this is a "look at my awesome fortress!" thread. I hope no one has anything against it.
Lets start with the DFMA
linkIt's not finished yet, but It's a good way in, and I'm not planning on stopping soon! Anyway, the idea for the fortress was born out of my failures to make a fortress under an ocean (I tried twice, with different methods) so I decided to make an artificial lake instead.
This is the fortress I came up with, and after 34 years the fortress is shaping up to become really good. One of the main things I wanted was a living district where every apartment had a view out to the lake through glass walls, and for this purpose I constructed the housing district that is in place now. It has, of course gotten some modifications along the way, like the barracks and food storage that is in the middle.
Another thing that I wanted to do was a cavernous entrance hall where the road to the trade depot ran over an underwater lake, and that has been accomplished as well with the entrance I currently have. I'm still using the temporary housing that was built to house the dwarves while the aboveground fortress was being constructed, but it has been gradually phased out, with only some personal rooms left in use at the moment.
The next thing that I'm going to build is probably some more entrance defences, with a ballista pointed at the entrance bridge and a firing tower for marksdwarves. I'll probably include a couple of catapults as well, and a direct stairwell to the barracks.
So, Questions? Comments? Suggestions? Criticism? Fire away if you've got any!
