If I wanted to play a completely ahistoric world I would play Civ 5 tbh.
Brrrr... Civ 5... Brrrr...
The reason I play this game is to play historical games.
Are you aware that "historically" Europe hand't a clue about how the New World was shaped, inhabited, technologically andvanced or even if it was a New World at all, don't you?
If there is anything "unhistoric" in EU is the race for the Americas beginning with every European *player* possessing abnormally precise knowledge of what they will find (probably derived by Ancient Atlantean's Knowledge Tomes). This, if anything, is unhistorical. If it is historicity you pursue, then welcome to this new expansion.
