The map would cover the whole world, yet you'd have to explore to find stuff out, and say if you're a European faction you wouldn't be able to go to the Americas until 1492 or something.

It would not get stupid like other all-time games like Empire Earth where you end up with tanks fighting knights, because your faction's progression would be controlled as in the previous TW games.
I would imagine by turn 200 the latest you as the human player would have beaten everyone else already, long before a new age dawned. Or else time would just pass way too quickly. I mean M2TW under VH can be beaten in 77 turns and you can own the entire map save the papal states within 110.
