Would we be permitted to play Aztec gods or only Mayans? Seems unfair that Europe gets 3 distinct Pantheons but all of the Americas only get the one.

I'll allow Aztecs, sure. They are similar enough to the Mayan ones ( they actually share some iirc) so I'll let it fly.

So dumb question, but how accurate to actual mythology do we have to be?

It should be accurate with some leeway given for storytelling purposes. Not dead-on-balls accurate, necessarily, but nothing that is a radical departure from the myths.
