We've all heard about area 51, what about if it happened earlier and they established a nation near the Aztecs? They could either start with maxed out techs or they could start out with medieval techs as perhaps they crash landed and effectively had to start all over again. We would need a new religious group that the Aztecs could convert to and eventually have events to conquer Europe once the colonisers reach America. They would start with the entire map uncovered.
I think this would massively add to the mod.
