I'm new here, but I've already picked up that Standard Policy is to tag questions with the system that you're playing in, and that the vast majority of questions can be closed a "Lacking details" if the system isn't specified.
Would there be some way to teach SE that "these system tags are special, and all questions must have one"? Meta-SEs already have that for bug, feature-request, discussion, and support. Can that system be re-purposed for this goal?
(If necessary, we could add a specific-obscure-rules-system tag, to cover the remaining tiny number of questions with no suitable tags - if such even exist.)
