Turning known RPG cities into Urbancrawls

I've been reading a bit about the urban crawl this week. I did find some other sources, but really the only one I want to highlight at this point is The Alexandrian's blog series. If I do a more detailed exploration I'll mention some other posts as well. 

What I liked about the Alexandrian's work is that it strikes (what I think is) the right balance between realism and gamification. What I mean by this is that some OSR people become a bit too hung up on - for example - replicating a realistic medival town. Absolutely nothing wrong with that, but it doesn't really cut to the heart of the question which is "how do I run a satisfying urbancrawl in an OSR style?". Another thing I really valued about his posts was the depth of research he did on both new-school and old-school source material. That sort of research really does show in the quality of the writing. Too many people try to do stuff from first principles and get stuck in the weeds.

Anyway, that blog series essentially lays out a framework for creating OSR style Urbancrawls for open-world games. I'm using it as a foundation for my own system, which I want to in turn use to "crawlify" some known, classic locations - first and foremost Menzobarenzan which is one of my favorite canonical cities. 

Once I have a bit more on that I'll post it here.
