Mostly all the time when i choose random civilizations as opponents the most common is that i get the Incas, the aztecs, the mayas or the Iroquis. One can wonder if the creators faovured this civs, as the indians were oppressed by the americans. Another thing that is annoying is that always when i play germans they start on bad lands. Often there is no river or sea in the nearby, so I have to search with the worker. And the land is mostly food and not many production-squares. Have you experienced that?
