America = 8
Japan = 4
Rome = 10 - 3 = 7
Spain = 7 + 1 = 8
America... unchanged. Do not agree they are not a late game culture player. Their media industry has been, and is still the strongest - and the film studio reflects this. Of course, they have not a very old culture, but have make the most of their past epic (western) and current trough film and TV. Maybe the pop music has to be shared with the Brits, the blue jeans not. Cannot give the +1 this time, tough.
Japan... unchanged: oxigen baloon was initially meant for them this time, but they have received it already. As with above, i disagree with saying packed cities are not a japanese disctintive trait... Just need to see any photo of japanese cities to comfirm a lot is going on in a few square meters. Maybe Meiji restoration was not the best name, howewer. I guess they just needed to get the name in somewhat.
Spain, +1: not really my first choice, but a reaction to save the science on the mission. Of course it clashes with the religious militant side of Conquistador / El Escorial, but that is what makes it a good depiction: to recognize there are flip sides to the same coin, dark and light, and the same piety can ve used to justify wars and to learn from the different (probably not by the same person, but a civilization is. Lot of people)
Rome, -3: Nothing against them really, but they have the most points and others needed some points to be defended.
