What is the best route for a protagonist who is host to an omnipotent entity (Inner God)?
Ruler: Just like Rimuru Tempest, the protagonist would create a nation starting with a village. But the difference is that there will be conflicts with a dictatorship and criminal organizations, as well as tensions with other nations. This will attract the attention of several powerful entities.
NOTE: Should I do something more contemporary or something like Final Fantasy XV (a combination of contemporary, medieval and futuristic)?
Traveler: The protagonist would be a Traveler like the Doctor from Doctor Who, but in addition to traveling through time and space, he would also go to the most diverse worlds (universes, multiverses, dimensions, planes of existence, etc.). Sometimes he ends up having to deal with some cosmic or apocalyptic threat.
