My build is getting a bit out of hand, fitting it meaningfully in a screenshot has gotten rather hard.
Anyway, might be interesting to see how I go about building.
So I ended up finishing the palace wing of my palace (at least the structure part, need to decorate rooms etc still.
From the entrance to the end I built a big throne room:
Dragon heads are kinda big, but I managed to fit one in the equally ridiculously big Map Room
Overview including my initial base at the bottom of the arch, for scale. The palace I built is barely visible here (it's behind the Derketo temple, which is the yellow or green(*) light beam)
I'd probably have to make a video of sorts to fit everything in without it feeling too disconnected or resulting in a truly ridiculous amount of screenshots...
In total there are 4300 T3 (Aquilonian) building blocks used in this (so far), of which 1181 are foundations (not counting all the Stonebrick for the ramps and the Sandstone Foundations used underneath to level out the terrain)
