Since all this talk about new demigods, I thought I kick an idea about for an expansion - Referee gods.
Such gods would be NPC's and represent a third team. They could provide balance, where needed and since they act entirely for their own amusements, what they do would represent a bit of randomness, hence making an otherwise unwinable game, winable.
I don't see how this would work on current maps, so new maps would probably be needed.
Thoughts?
