Hi, I'm so glad Wanderhome resonates with you! So if I was playing a game where I was mainly avoiding sprawling natures, my approach would be to generally not select them unless a picklist prompted me to, and then once selected interpret them through a metaphorical lens. Like, what is a forge metaphorically about? Is there a space for a place that contains many people coming together and intermingling, even if it's not a literal metropolis? Another approach might be to draw more heavily on 3rd party natures or those in the stretch goals PDF, all of which can be found here — maybe if there's no equivalent to a metropolis, you could pull in a beach, fallen star, or shade.
No matter what, I hope your wandering goes well!
