The Aztecs are surprising. If they are done the right way they could be fun without being too wildly inaccurate. This would require severe limitations upon the number of European troops available to send to the new world. If we have to recreate the conquests of Cortes and Pizarro with hardly more men than they had it could be a lot of fun to try. The 1530s end date also makes the slate cleaning effect of disease a non-factor in an Americas campaign. It could work something like this: You spend time and money to buy an event that lets you send an expedition to America. A Crusade sort of, but with a very small force. When you arrive in Mexico (if you arrive), you encounter the Aztecs and either make them allies somehow or you attempt to take Tenoctitlan by force with your tiny army in an effort to steal all the gold. Make friends and you gain regular trade income. Plunder the place and you earn enough money to crush your enemies for decades. Fail and whole thing is a bust.

I hope CA resists the temptation to make the Aztec soldiers into more than they were. Numbers were the only thing these people had going for them. It might have been enough. It should never be possible for the Americans to win a pitched battle against a large European army. On the other hand, that’s a moot point since it should not be possible to get a large army to America at all in the early 16th century.
