Hey hey all, so this just came up on my Twitter feed, from the same coders who created Uncharted Atlas, another piece of code I follow.
Metropologeny appears to be a series of procedurally generated city and settlement maps that honestly, looking through, I would expect to see in OGF or real life! I'm amazed it was all done in code really! Thought it'd be something of interest for everybody to see, I'll post another link below, and a link to the Uncharted Atlas, which is similar in that it's procedurally generated countries. I would seriously suggest you check them out!
