Oh, almost forgot.... native colonization became REALLY REALLY REALLY REALLY slow. Colonial growth is now based on tech level. At admin tech level 1, you're getting 10 colonists/year. I'm actually considering using other natives to help expand my empire, by either selling other natives my colonies or by colonizing, going to war with a native near the province, letting the native take said province, then colonizing somewhere else. But otherwise, it's pretty much worth it for me to not fully fund colonies, and instead rely on the % chance of my settler successfully colonizing a province (not to mention any boosted colonial growth resulting from completing a colonize mission). Yes, that means keeping some nations alive and even... helping them grow! *gasp*
