Certainly not. Take a look at Blenders new Geometry Nodes system.
I've gotten absolutely incredible mileage out of geo nodes for forests and cities. Once you get used to the peculiarities, geometry incredibly superior to using particles and heatmaps. And I'm just a hobbyist! I use Blender for gamemastering, but haven't ever been paid to do it . . yet.
(If that sounds like fishing it is totally fishing. How does a middle-age MilStdJunkie break into the modelling / simulating market?)
Did you do any street-level renders? I realize that it's completely, totally a different kettle of fish, the detail you got here would murder the entire world's computers if it had 1m scale detail.
Fabulous, fabulous work. Amazing. I did something similar for New Amsterdam ~1660CE, for "Providence", a Lovecraftian horror game set in colonial New England. But New Amsterdam and Seekonk in 1660 is nothing compared to this, Tenochtitlan in the immediate pre-contact period.
