Manly-like. Think of a world that delights. Take “Mother Warrior Goddess Queen.” The world of Amazon warriors in ancient Greece is really just a world where naked lesbians kill people with axes.
It naturally contains all three elements of the holy trinity: sex, violence, and comedy. What else do you need? For the manly male reader, include a blood-pumping revenge story. For the hot female reader, include a heart-rending love story. Drop in all the funny bits and polish until shiny.
Release it into the world. Anyone who reads your book in one weekend and considers it a five-star work of pure bliss is your friend forever. Anyone who doesn’t read it or doesn’t love it is not worth ever spending time with. It’s that damn simple.
So don’t think so much. Just do it.
