All right, this is the list of genres you can use:

A couple more ideas:
-Mythologies (like Roman/Greek mythologies though Asian ones can fit this too)
-Fairy Tales (can't remember if you did this, but if not another one to consider)
-Westerns (not sure if very much people here read it and it's a pretty niche genre)
