Recently, a user posted a question asking for a specific user's house rules. This question was promptly closed as off-topic, and I feel like the community made the right decision, but I can't put my finger on why.
Looking at our What topics can I ask about here page, the question seems to fall squarely within the description of an on-topic question for this site: It's about role-playing games, and requires the attention of an expert; And it's definitely about "RPG rules or mechanics" as well as "Techniques for running or playing RPGs." The page does list a few reasons why a question might not be appropriate, but the only one that might apply is about potentially becoming obsolete, and that one seems a bit of a stretch; KRyan is well-established as a GM, and their list of house rules is therefore unlikely to change much.
Our What types of questions should I avoid asking page doesn't seem to have any relevant guidance, either: The question is reasonably-scoped, isn't an invitation to discussion, has a single concrete answer... I can't find anything there that suggests this question should be closed.
We would have closed this question as 'Too Localised' back in the day, but that close reason doesn't exist any more precisely because it was too wishy-washy and subjective - so presumably we must have a more concrete one. Perhaps I'm just not making an obvious connection between what the help pages say and the features of this question?
Why was this question closed? I do suspect it should have been, but we need to know why, because if it's a reason that isn't explicitly stated on our help pages, those help pages need to be amended.
