I can’t speak for
@EzekielRaiden, although I think we share similar sentiments on this issue. My take is that generally a GM
shouldn’t attempt to author highly specific settings and then look for a group to play them, because that specificity causes more harmful issues than it adds positive additions to play.
If you like to solo worldbuild for fun, go for it. If your group has been together since the Pliocene like @Lanefan’s and is cool with you building out a highly specific setting, great. Otherwise, I think it’s a poor idea.
