Flip it.
Gamers are gods
gods-still lower case, referring to being vastly beyond human capabilities in a domain.
I think the Ellimist-God doesn't work when considering God as an all powerful, unbound entity that can do anything, and the source or substance of everything.
Rather we must compare to gods of old: The god OF fire, god OF the seas, god OF death.
No mortal could match their prowess within a gods domain, but the gods themselves are gods of a certain thing, not all.
Again and again it's said the Ellimist, has his limits. He can do a lot, but he is not all powerful.
He has more domains, can play with time and matter and species, but he has rules and constrictions, self imposed or otherwise, in the way of other gods. Even Zeus could not change fate.
It's a human with an ant-farm, you can do a lot, change them home, squish em, but your bound by, time, physics, morals, ethics and laws etc. You can be godly, but really, your not God.
And so it is with the human games: your sims or whatever. You can do a lot. But all you're really doing is playing with the toys you have. You seem powerful, but only from the limited perspective of the what's available
I think overall she was careful not to introduce a God character-a character that could do ANYTHING, and that's the difference between God and god of, imo. By nature, gaming makes you a god OF. That's part of why we do it. I think that's the parallel, because that's what's understandable. A God, is incomprehensible. A god is just playing with, we can understand, even if we don't sympathize.
