Are worldbuilding questions on topic?
On SE, Writing and Worldbuilding are separate, and it works pretty well. I, however, use the Worldbuilding SE significantly more than the Writing SE, and as I reduce my usage of SE I would like a place to ask such questions.
In This Question on-topic includes "Questions about fiction..." which in my opinion covers Worldbuilding in a very broad sense. But it also easily could not cover it.
Before I go and ask worldbuilding questions of the fine people here, I do want to make sure it is something that's welcome here. I see that there is a world-building tag, but that only means someone made it as a tag.
