"Tourism: Further Benefits from Tourism when Influential with another Civ
Science (from Trade Routes)
Familiar: +1 Science per trade route
Popular: +2 Science per trade route
Influential: +3 Science per trade route
Dominant: +4 Science per trade route"
This will significantly help CV strategies that don't rely entirely on focusing on Science. If you focus on Tourism early, you tend to stall out on science, especially on Deity.
It may also make it more possible for AIs to achieve CV, something I'm not even sure is possible right now.
"Spaceflight Pioneers: Remove +10 Science in Capital; add free Great Engineer and Great Scientist instead."
Wow, this is good. This makes Order hard to compete with IMHO.
"Civ-Specific Balance
Japan: Give Japan an Ocean start bias
Japan: Japan: Samurai can build fishing boats.
Japan: Bushido has a new additional effect: +1 Culture from fishing boats and +2 Culture from atolls.
Japan: Zero no longer requires Oil"
This makes Japan very intriguing for Continents and Archipelago maps.
"Congress: Made Diplo Victory more difficult by increasing the delegates needed to win (2 more on Duel, 7 more on Standard, 9 more on Huge)"
Yay! This was sorely needed.
"3 New Pantheons
Earth Mother: +1 Faith from Copper, Iron, and Salt.
God-King: +1 Culture, Faith, Gold, Production, and Science from the Palace
Sun God: +1 Food from Bananas, Citrus, and Wheat"
This is great. Copper was kind of the worst luxury. Although did Salt starts really need a boost?
God-King will be good for OCC. Sun God will be very powerful... population explosion!!
"Great Admirals now have a "Change Port" command."
Good! This was very annoying having your admirals spawn half a world away.
"Fix a legacy bug that prevented the AI from ever putting together offers for a luxury that a human player now has available for trade."
Finally!!!
"Military AI: Civs with very high FLAVOR_OFFENSE settings (7+) will buy military units with spare gold more frequently. Will boost the number of early attacks we see, especially on high difficulties."
Rut-roh!

More thoughts later, but so far very intriguing!
