What to take from Portugal?? Release morocco? Take Lisbon and some others so I can vassalize next time? How do I get their colonies? Through diploannexing? I can give ceuta to Algeria, other land to leon or core it myself.... lot of options.
you need to own entire Iberia and genoa for yourself, for trade reasons. So whatever you core in Sevilla trade node, core it for yourself. You got two options. Either put Portugal under 100 warscore, and come back once truce is out (and hope their CN don't declare independence), or plain taking 100% warscore in provinces, inlcuding ALL their 0% overextension colonies in Africa and wherever. You can Always imperialise independant former CN late game. But getting the CN for free is Always nice.
You wil ONLY get their CN if you FULL ANNEX them. Do NOT vassalise them or CN go free. Making vassals of nations that have increased coring cost is BAD idea, as you will pay extra diplo points for that ioncreases coring cost also. Transfrer occupation of everything OUT of Sevilla node to Algiers, and give those provinces to Algiers.
Here's the map 1603. So much to summarize. Right now at war with Portugal, wurzberg, cologne. Need to decide what to take. I can force release of morocco, maybe take island/cape colony. If I vassalize and diplo annex Portugal I get their damn colonial nations correct? How much development can I vassalize? Cologne is an elector looks they are being converted to protestant. I could vassalize them if want to aim for burning down the HRE AE wise and getting 3 or 4 elcectors vassalized.
Didn't the league war make empire catholic only? If elector goes protestant, they will lose electorship if so. Keeping vassal electors might not be needed, if you avoid taking lot of AE with HRE.
Your goal should be to pass reforms and get revoke priveilegia. Eating HRE yourself is the worst thing you can do actually, as you pass up a free vassal swarm horde then.
I got actually no experience whatsoever playing reform game with the 'normal' IA farm ways though, gonna need someone else to comment on best approach
England truce is up in 6 months. They are allied with Norway, bohimia, Saxony, danzig, verden. Do I snatch danzig to stop PLC forming or is that not a concern? I am in position to smash them, maybe annex 2 province Norway? Actually Norway, ottoman, England, palantate looks like the way to go. England attacked cusco in south America, half its 15k troops are there lol.
You can play PU game to get Poland/Sweden in a PU. that is what I would do. Norway is bad idea as vassal, as they get increased coring cost.
You must core england yourself, to dominate english channel trade node.
I actually would ally Poland, if they are rival to Sweden and/or Russia. Sweden will likely ally England at some point, and if Poland rivalled them, you can call them into your wars.
Vassalise NOVGOROD. they are one of the best vassals you can have. Full annex them, and release them. They will take historical ideas then, with administrative, religious and plutocratic. They get an extra +1% missionary strength, making them too good to pass up. Integrate other vassals, and try to release NAJD. They are another good vassal, as long as you release them with historical ideas. They are same as Novgorod, admin and reliigous. Ideal for letting them convert everything to catholic, after forcing them to become catholic.
Here is asia. Brunei is in coalition but I made a claim on sulu they are allied with so I can attack. They have 1000 ducats

. Should I annex sulu and feed brunei to Ayutthaya next truce or core it?
I have dues vult up on korea allied with ming. I can take land from ayuttahya to get claim on Tonkin alied with lang na(in coalition) to feed them to ayatthaya.
Bahaminis is attacking everyone..allied with delhi, malwa, and sind. I want to protectorate Bahamis I think. If I want to protectorate bahaminis I have to take their allies capitals and peace them out then get 100% on bahamais?
Protectorating big nations in Asia is good idea, as you can vink on 'colonial war in war declaration screen. All your protectorates will then JOIN the war, which can lead to a swarm of big protectorates eating Asia. You need 100% warscore to make a protectorate. Peacing out allies isn't needed, but it will make acceptance of such a peace faster. You can annull their alliances, and feed them to your protectorate once truce is gone. Only vassal I'd take in Asia/africa is najd.
Make sure you use subject interaction for protectorates, ansd ask for divert 100% trade power.
Africa
Mali is in coalition. nupe, air, and Timbuktu are allied. I was thinking of pretectorat nupe or maybe air as purple is pretty...
Make sure you get all provinces in gold coast trade node, and leave the rest till last. West africa really isn't worth the fuss until late game imperialise/admin efficiency stage. And they will all westernise. But it's up to you.
I have to get my vassals annexed asap...Algeria and wallachia suck with increased coring cost. I forced them all to catholic but that didn't seem to reduce diplo annex cost. I am thinking of dumping exploration right now and taking influence. I can get the third idea about 10 months later for -25% diploannex get rid of wallachia then get the -20 policy and try to time 2 annexations while that is in effect.... next idea would be expansion or quantity perhaps?
Never take ICC vassals. Ever. Switching exploration to influence seems good idea. Integrate small vassals after you get the -25% diploannex, and then integrate large vasals late game once you filled admin+influence for the policy, and once you have admin efficiency. Once you got admin effficiency 3 at 1750, and that policy from admin+influence, you can integrate enormous vassals for a few Thousand diplo points only.
Regarding enxt idea choice: take offensive. The siege ability +20% will help a LOT to shorten siege duration. And it gives discipline and extra forcelimit, which can be handy also.
Classic wc ideas are admin religious influence diplo offensive quality.
