I am seeing alot of questions that are very broad like in case of X what would happen, or if the world were made of X then how would life evolve?
I think we need to be extra careful to ask more focused questions like:
Population range for a booming/dying frontier town
This question is focused wants to know what would be an approriate population for a former boomtown that is now just hanging on.
Compare the focus of that question to these:
What effect would elemental magic have on the work force
What and how main technological breakthrough we have today could be replaced with magic?
I hate to have an outright ban on hypothetical situations when our problem is too broad of questions.
Should we be trying to salvage these too broad questions? If so How?
