It would be a good idea to have a bit more focus outside Europe, especially in Asia, Sub-Saharan Africa, and the New World. The only problem I see is that these areas, especially Asia, had much different outlooks and issues than the western nations in this time frame. As much as I would love to see some flavorful Chinese or Japanese events and history happening, I feel it won't happen due to the nature of the game and how much the gameplay would need to change to accommodate it. I would also fear that we would just see a few unification, more revolters, and maybe a couple of decisions, which while welcomed, isn't really enough to make a whole expansion out of. If it was done well, I'd support it though.
