Hmmm. Not very easy to protect archers and artillery vs aztecs. They react to them very aggressively and will charge them down, attempting to plow through my combat line in the process too. Their weakness is their mobility - they're easily flanked by cav.

I usually fight them with tons of heavy cav and try to do downhill charges. One downside of the new world is that it's packed with dense jungle - bad for cavalry.

Anyone tried setting capital in New World?
