Introversion’s procedural city generator turned heads when the first glimpses of it were released in 2006. Unfortunately, the Subversion project was eventually canceled, but not before inspiring a lot of people who would go on to build their own city generators.

Its important to remember that procedural generation doesn’t solve all of the problems. In fact you can spend a lot of time building a procedural generator only to discover that the thing you’re building it around isn’t much fun. There’s ways to mitigate this, but like most creative projects it can sometimes be hard to see what you’re building before it’s done.
