*makes backup of 1.5.1 for current game*
That is a lot of changes. Although it isn't mentioned in Dev Diary 10, the Power Projection mechanic sounds pretty important to me. The changes to goods produced could also be pretty important, as well as AI improvements and (potentially) the changes to buildings.
Overall, it sounds like a good patch.
Speaking of expansions, does anyone have screenshots of what a randomized new world in Conquest of Paradise looks like? That seems to be one of the major features there, but I'm not sure if it's just that the native nations in the New World are randomized, or the internal provinces, or what.
Also, it looks like the changes to ideas in
dev diary 9 also affect the base game, without Wealth of Nations. I wish it would
I wish it were a bit clearer what's in the expansion vs. what's in the patch. The EUIV Wiki helps some, but it isn't perfect, either - it indicates that the vassals/protectorates window is in Conquest of Paradise, but it's present in the base game as well.
If you get over 100% overextension, you can get some unpleasant events. I found this out via getting 104% overextension once while unaware of that. Supposedly the events get more nasty as you get higher above the limit. So in that regard, it's like badboy in EU3, where if you're just slightly over, it's bad, but if you've got 250 badboy, it's
very bad.
Also, if countries get outraged enough, they'll form a coalition against you, which can be pretty powerful. Playing a Milan and getting France, Austria, and a few smaller neighbors in a coalition against you leads to some tough times, particularly since if one of
them declares war on you, they all join (not just if you start a war against them). It might not be as big of a deal as the Commonwealth than as some other countries, though I imagine if Russia, the Ottomans, and Austria all joined a coalition against you, it would be a good incentive to slow down expansion.
Also, the new patch will change Nationalism to always last 30 years, even if you core a province. That'll make expansion a bit more difficult, and it's kind of surprising IMO that Nationalism went away as soon as a province was a core in the first place.
