No coalitions has been formed in this campaign. I just conquered them nicely. Most of the time my overextension was below 100. Even thou I managed to install von Habsburg on English, Spanish, Swedish and Portuguese throne. I had to force PU and diplo-annex three of these nations and conquered Spain manually. I only trucebroke Spain in this campaign (so colonial nations couldnt break free weakened Spain).
Ideas: Diplo, Religious, Influence, Admin and rest changed a lot between exploration/expansion, aristocratic/quality, humanist.
In this run I also got The Rising Sun, That's a Silk Road, Master of India, Trade Hegemon, Georgia on my Mind, Spice Girls, Fantastic Collectivist, AEIOU, Laughingstock, Colonial Management, The Ostenders, World Discoverer and Electable! achievements for the first time.
