Okay, time to try and do the calculations.
For ease of calculation, count CoTs separately from provinces. So if you have x european provinces, y colonials, and z cots, you'd get x * 1 + y * .25 + z * 2 prestige.
Also guys, I am not counting the increase of income from 1492 since technically that's a zero and would lead to infinite prestige. But starting next session we will start those calculations.
Winning wars against AI doesn't count for anything as well. Similarly, losing a war vs an AI also doesn't count.
Please let me know if I've missed anything, or if you think something should be changed. Now's the time to discuss, and nothing is set in stone, as we are all aware that the rule set is untested. Also check over your individual tallies and make sure I didn't make any mistakes.
I took the liberty of adding another rule that grants one power point for a victory in which you didn't take land or vassalization. That way nations will still be properly rewarded for winning, even if they didn't succeed (or want to) take land. So England and Austria should each get a point for beating me this session.

)

+5 for guaranteeing independence of BB and fulfilling obligations by dowing Poland. As a note here, I don't think in general that this should count, but BB is small enough that Poland is a huge threat to it, so I'll count it. But in the future, I'll be very skeptical of guarantees against AI nations.
