I like the Modern Day scenario. It lessens the amount of research we'd have to do. xD

So the vesseled gods would probably be on the protagonists' side, correct? And the others would probably blatantly display themselves as gods. We know how those Egyptians were with their whole "I am a god!" shtick, amiright?

We could also work in Illusion's idea: the only advantage the protagonist humans could have is the fact that they know the world better than the gods do, and the idea that the gods are perhaps "afraid" of the world the humans were capable of creating without their help. In fact, maybe that's what angers them to take over in the first place: they were getting a bit jealous of the advancements the humans made without the gods to guide them.
