Ok, so the question, Is there a list of all Halo-related reading?, was closed and then re-opened, after a bit of discussions in the comments section.
The question was then re-closed very soon after. See the revision history.
And the Off-topic reason being:
"Requests for lists of works or recommendations are off-topic as they do not fit our questions and answers format. Feel free to ask about people's favorites in chat."
Why was this question closed?
What makes it "off-topic"? It's definitely not asking for a recommendation. It's asking for all the relevant source material for that certain canon.
- Definite list
- On-topic (Halo is very Sci-Fi)
- Not asking for our 'favourites', etc
Related (on-topic) questions:
- Where does the background story in A Song of Ice and Fire come from?
- How many Marvel Earths (Universes) are there?
- What should I do if I want to cover 100% of Star Wars EU but don't want to play the games?
- Is there an "official"-ish complete chronological order for Star Wars C-canon material (books+comics+games)?
I am most definitely not asking for people to justify themselves having gone against what I've said. I just want to get a consensus on whether or not this is on/off-topic and why.
