Yeah, well... New Genesis is a pristine Garden-of-Eden-like planet, and all the gods of New Genesis live in the orbiting city (I can't recall if "Supertown" is the official name, or the nickname for the city by the younger generation of gods the Forever People are a part of).
But when Superman heard the name, in the story he was feeling alienated on earth, and he sought out the city to find a culture of others like himself. It's a good story, portraying a side of Superman not seen before.
I forgot to mention, Lothar, that while unresolved at the end of FOREVER PEOPLE 1, Superman finally got to visit Supertown and see what he was missing in JIMMY OLSEN 147.
Fun, but also

-worthy.
