Define what is world building

There's a handful of communities on ttrpg.network that might be relevant:

• !worldwrecker@ttrpg.network
• !rpg@ttrpg.network
• !micro_maps@ttrpg.network
• !rpgcreation@ttrpg.network
• !askgamemasters@ttrpg.network
• !DMWorkshop@ttrpg.network

Etc etc

In my experience, the best way to ask about unpopular (here, on Lemmy) stuff is to make a post in a generic community. Discoverability sucks here and not many people are on here too so niche communities are often deserted.

So, if you make a post on popular lemmies like this one, you have better chances to receive a helpful response. I'm not sure how the situation with writing communities is, maybe they are active enough to be of use for you!
