I recently found out that there are tags like legend-of-zelda-series, grand-theft-auto-series and half-life-series, and I was wondering:
- When should the [*-series] tags be created?
- What if there is only a single question that requires the tag? It should be created on this case?
- If the answer is no, then how should the question be tagged?
- Should they be requested on Meta or just created as they are needed?
This is related to the What is the Chronological Order of the Sword Art Online Games? question that I asked a month ago.
