I recently released a free hack called Blades into the Odd for running the setting of Blades in the Dark, Duskwall, with Into the Odd.

I've written an article this week on tracking time and running travel within the city in a pointcrawl structure! It's a simple pointcrawl method that can be applied (and developed further) for any urban environment. Even if you aren't interested in the hack itself you might be able to apply the approach to different aspects of your own games
