Dealing with what-if history for the Americas can be a pain when it comes to dealing with any scenario that results in Native Americans not being decimated by Europeans. A large amount of pre-Columbian history has been simply lost or destroyed. And we're only finding now that there were some civilizations in the Americas that could have been much vaster than realized (such as the new discovery in the Amazon Rainforest).
So what could have been a best-case scenario for Native Americans? Is there any way for them to avoid the dooms of plague and genocide? And if they do, what would the continents look like now?
