Brief Portugal AfterGame AAR 1492-1668
Well, my old wet dream was realized in this game to play with good player in pair for Iberians to let Portugal go naval and Spain - land and not to lose the sea and CoTs.
The worst was the lack of strait between Gibraltar and Tangier, which would allow to increase greatly portugal naval limit if given Andalussia and Gibraltar. At the other point Kasperus map has much more provinces for colonization, so it guarantee to appearing CoTs in certain areas, which you can`t hope in vanilla.
It was planned to go reformed, which demanded to be small for a long time not to convert colonies after all. Spain should protect Tago not to let anyone to steal maps, and first 50-60 years of the game Portugal can`t help to Spain and Austria, otherwise it took part of Spanish troops.
At the first session, plans were realized - Portugal teched to NT9 and LT9 as first priority to secure maps and assault pagans. As usual small CoT appear in Sao Tome, Zanzibar was conquered. Gold was taken from Ashanti. Serfdom was increased, so Portugal Empire, despite on a lot of uncovertion provinces, has very small stabcost comparing income. Income raised from 27 ducats to 45 mid-session and 94 at the end.
At the second session, time for Africa gold and Timbuktu came. Portugal had great 5-5-5 conqs and LT9, some MA - pagan were done very easily. Small CoT appeared in Puerto-Rico, Calcutta was conquered, Keiptown CoT appeared too. All census taxes were sent to merchants and TPs. Infra 4 and Infra 5 were done to 1532. Income increased to 163 ducats. From this time Portugal could finally earn enough ducats in treasury. Before Portugal had only 87 census tax income.
Next session 1532-1554, Portugal owned 8 CoTs already. Converted to reformed. Another great conq conquered China to grab Shanghai and Guandong before CoT appear there. So there were only following non-Portugal Asian CoTs (i don`t count those which OE usually takes) - Mascate (capital of 4 provinces), Malacca (capital of 7-8 provinces), Pegu (capital of 5-8 provinces), and capital of China.
LT14 and NT11 were reached, as good target to stop and economize. Next effective one were only NT17 and LT18. Trade 4 and Trade 5 were done (Trade 6 was on more than halfway) and 8 refineries were built. Income was doubled to 340 ducats. The help was done actively for Spain to defeat the France. In all wars vs France Portugal aid was one of the most important, not only economical, but military too, using good leaders or CRT. Spain could keep France and don`t make own position dangerous, which was important for Iberians independance after 1630.
Next two sessions 1554-1586, i was on vacations, and Deil subbed me, using my exact typed plan. For this time Iberians were in wars vs France and OE, defeated France once, but in 1586 France dowed again and had +80WS on Spain. Portugal didn`t interfere much, having +11 WE after war with OE. Income was raised by 100 ducats to 430, LT18/NT18, trade6/infra6 reached. Portugal started slow colonization finally, though was rather small - only 32 provinces.
A lot of ducats went to wars of Habsburg, besides gold rule gave +6,5% inflation.
In 1586-1604 Portugal started actively great comeback using CRT and nice fire leader to free Spanish provinces. For several years we achieved from -80 to +50WS on France, so peace was signed for 2 provinces of France. When the WS was near 0, France was offered WP, but refuced. OE was on vacations same as me and FAL, and despite bigger expansion in Italy to border France !!! (Venice was left 4 provs only) OE had a lot of WE, and was almost stabhitted by Russia, who took unprotected Siberia. Bob returned and wiped out Russians easily using CRT, but Austria dowed him and grabbed back Tirol, gold province and another one, so OE lost land access to own Italy lands. They were sold by low price, because naval advantage of Iberians would let to grab enough WS and stabhit without land fighting.
In 1604 Portugal reached 21/21/7/7 techs, max possible without going ahead of time. Income 490. Offensive 9 and quality 9 were reached. Land was 0, Aristocracy 1, only one click to cheapest warships.
Portugal scared a lot of coming uber-leadership of Dutch and England, and realizing own small naval limit, teched to costy warships efficient time to be ahead of competitors for securing of own CoTs. As suspected, Dutch and England had more and more close relations, which would become future threat for Portugal, because for both of them portugal cots were very good target to unite and strike using uber-admirals. So when Dutch and England got big conflict with Scandinavians, Portugal aided Scandinavians.
Colonization was continued on better rate now. France dowed and dowed again, but it didn`t take much efforts to kick them back now. It took much efforts to make them peace. After 1600 Portugal got more inflation because of gold rule, summary - +15,0% inflation from gold rule. No deflation events happened during the whole game for Portugal and Spain.
At 1604-1619 Scandinavians decided to take a lot of core provinces of Holland, but were ready to sell them at good price later. That kept away NL to look for hostile against Iberians, and soon they asked Spain to be their vassal. Austria was funded to kick OE and made success to regaining more provinces. Portugal teched beforehand in future 8/8 trade/infra. As well we colonized and conquered pagan Benin and converted. Cyprus, Albania was annexed, Rhodos was gained.
Spain lowered BB much faster than Portugal because of Aristocracy DP slider and better monarchs, so they annexed islands in Med to give Portugal back.
That were agreement signed with OE to give NAP for 100 years (so they secure Alexandria and coastal attacks), and instead they sold 3 islands for 1500 + ref on Crete for 1000.
That let Portugal grab all islands before Eng or NL become enough strong to buy them for own limit and cutting Porto limit. As said, Portugal politic was to go one-two steps before NL and Eng.
In 1619-1641 Portugal reached 26/26/8/8 and teched enough to 9/9 when 1690 comes and time for 9/9. Austria was funded heavily to keep OE busy and waste a lot of own money to stop OE development. Well meaning situation in 1586, it works very good - OE didn`t progress much for this times. And because of that it was seen like OE won`t appear in China and Timbuktu in the end of the game, so no worry about this CoTs for Portugal. OE was weaken and thought only about future PE.
Spain was funded for 5 refineries.
In 1641-1668, last session Portugal calculate some things not to go ahead of time and came to conclusion that before 1690, Portugal will need to spend at least 200 000 ducats of cash

About 10-15% is enough to invest LT/NT to keep at modern and in 1690 it was needed to invest something in future 10/10. Colonization was done at full speed with 6.8 colonists. Income raised to 600, 700, 800 ducats and almost reached 900 ducats at the end. Whole Benin was converted (about 15 provs). Islands of OE were transferred to Portugal, and ship limit became about 750.
England was subbed by Aladar in uncooperative mode, ended in embargo of each other, which gave me free hands to go for Ireland despite 3-6-6 english admiral. Spain dipannexed Venice, so Portugal should get Veneto, Ferrara and Ionia, after that Portugal would have 1000-1100 ships limit.
13 refineries were built, insane amount of money were sent to Austria. While Deil subbed them, he went to win, but Ear couldn`t do, so the result was WP. Not bad too, meaning OE left with DoTF and 15% bigger techcost.
At the end Portugal had over 800 warships at limit, built a lot of forts, and still had 40K ducats in treasury.
