In our tags, we have campaign-development for working on the sweeping project of the entire campaign world. We also have encounter-design for small-scale encounters.
Creating a city made of illusion that won't be quickly figured out has been giving me some trouble edit-wise, because it needs a tag that's in the middle of those — it's not the entire world and it's not just one encounter, it's a single location — and I've been sure we have one and trying to recall it.
Apparently it might be dungeon-design, which has a tag wiki of:
Questions about designing location-based adventure environments, both above and below ground.
... "Dungeon design" is a terrible name for this though. Most environments we'll be working on aren't dungeons (even D&D is notorious for regularly featuring neither dungeons nor dragons). And the name "dungeon" as a metaphor only makes sense for a narrow selection of RPGs (D&D and its derivatives).
Can we produce a better name for this tag? I am not sure if [location-design] works, and not in a frame of mind to work out a tag name myself.
(I don't think we need a new tag, hence the proposal for a rename. We don't need one tag for location design of literal dungeons and another for non-dungeons, especially since they often use the same patterns anyway.)
What should it be called?
