I did this awhile ago, surprised I never posted it here. I wanted to see what a MFCG city would look like with some elevation, so I put one in Blender.

Won't claim to be the greatest at Blender, but this was pretty fun and not that hard, thanks to the city viewer providing the initial 3D shapes.

I remember this city from your post on reddit :) It got better lighting and tiled roofs - looks cool!
