I like both. And bear in mind that Greek and Norse just happens to be the civilizations so far. If we do expansions, we'll expand to other real civilizations as well as made-up ones.
And in terms of the game, there's quite a bit of humor in general inherent and that's something I'm trying to play up some with the woes. I also very much prefer the idea of random dudes you supposedly rule over causing problems for you -- that whole free will angle, and so forth. That makes it feel more like a god game, whereas if Loki is messing with me that feels... not like a god game, more like I'm competing with a rival.
