A couple of thoughts about categories that could be interesting but I'm not quite sure how to name them...
Something along the lines of "lore-heavy" could be nice, to indicate settings that have a whole lot of backstory, worldbuilding, background info, that sort of thing. I'm just not sure "lore-heavy" is the best thing to call it, because it sounds... heavy. And I'm not sure if everyone would immediately read "lore" as meaning "setting background info."
For tone, something marking the duality between "grim" and, say, "warm and human" could also be nice. (The latter isn't quite the same as "lighthearted"!) (Granted, I'm trying to write something that's both, so I have my work cut out for me...)
I noticed that "nonwestern setting" didn't make it in? I do see that it's sort of a non-category in that it's defining something by what it's not, but considering that so much fantasy and historical fiction are based around western culture, a lot of times I like to specifically seek out something that either has a different inspiration or is designed to be distinct.
I think it might be worth splitting this into different categories
Perhaps call it "nonbinary protagonist option"?
That one's my fault it was one I added to the suggested category list and it looks like my typo got copied. Sorry, everybody
Edit: Is there a way to view the tags on a dashingdon game without just checking different filters and seeing if it's still up? If not, I would consider that useful.
