So, now we've got your huge comprehensive list, we start narrowing it down. Because we can't have all of those, and if you want Tapas to take this seriously, it's got to be something more manageable and only those with the biggest followings/common will actually make it. Please anyone writing/creating in these categories don't take it personally, this is just me saying what's likely on Tapas.
So, we start by putting in an Other/Misc category for people who don't fit into something else here.
Action (Change this to Action/Adventure, which is a common group)
Adult (Idk what you intend this to be. If you mean aimed at adults, age ratings would help, if you mean contains sex, we have a Mature section and if you mean Erotica, that's not really allowed because the focus is sex)
Adventure (Again, put this with Action)
Anthology
Anthropomorphized
Art
Biography
BL
Comedy
Crime
Drama
Essay (I'm not sure how many people are doing essays, but it can merge with non-fiction or other, not big enough)
Experimental
Fairy Tale (Probably fits into another cat most the time)
Fantasy
Folktale (I would combine this with Mythology)
Gaming
GL
Gothic (probably not a big enough genre to justify it's own thing)
Horror
Joke-a-Day (probably fits with Comedy)
LGBTQ+
Memoir (should probably go with either non-fiction or biography)
Meta (is this a big genre on Tapas? never seen it)
Mystery
Mythology
Non-Fiction
Poety
Politics
Psychological
Reference (if you're going to have this it should probably be with things like Tutorials or a misc/other cat)
Religion (I'm not sure this is big enough to be it's own unless everything ft angels/demons is in it)
Romance
Satire (Could possibly be merged with comedy or politics in some way)
Sci-Fi
Short Story
Silent
Slice-of-Life
Sports (this doesn't seem big enough to come out of SoL, although if anyone has some good sports comics, please direct me to them)
Spy (again, not big enough, probably goes in action)
Superhero (this is actually huge and something people have been asking for)
Swashbuckler (not big enough)
Thriller
Tragicomedy (goes in comedy)
Travel (not big enough)
Tutorials (can be put in with references)
War (I feel like this should be a sub-category of another, but I do know a lot of people write it)
Western (again, not sure this is big enough, but giving it the benefit of the doubt)
Obviously that's just a rough thing, but you can't expect Tapas to do a huge list of all genres. Some have to go, and only the biggest are realistically going to stay. A way around this is something of a tier system for creators when selecting their Main Genre. If it's Fantasy, you then get an extra choice to pick decide on sub-genres like Urban, High, Medieval, Dark ect. Or SoL it would drop down to something like Sports, School, Work, Home ect.
Also, some of these like Short Story and Anthology should possibly not be a genre but something else to select when creating. That way if you have a Fantasy Anthology, you can tell us its mainly Fantasy and then it's marked Anthology when you search. Something like a check box for Anthology, Short Story, Long Story(?idk what you'd call that?) when you make it.
