Fantasy/Sci-Fi
It was a normal earth until the dark ages, when people started developing superpowers. They used the superpowers to rise to noble-hood, and this system of democratic monarchy was kept till today. The superpowers also allowed great technological advances.
Not incredibly limited. AI is outlawed, but pretty much everything else goes.
Superpowers do exist, but often have some sort of limitation.
