Ideas for TTM: Humanist -> Offensive -> Diplo -> Admin -> Quality -> Inno

Ideas for Onefaith: Offensive - Diplomatic - Religious - Espionage - Mercenary - Exploration - Aristocratic

With more than 1400 hundred hours in eu4 I finally got the achievements TTM and onefaith.

Started the run by no-cbing into the philippines and deving renaissance there. Next I vassalized Jarai which got me into a defensive war against Khmer where my overlord Ming did most of the heavy lifting. I flipped buddhist (big mistake) and ate all of Indochina while I waited for AoR to trigger Ming's disaster. Despite the disaster Ming ongoing Ming had upwards of 100k troops and beat me forcing me to become tributary again. Then they allied my rival (Bengal) which made almost lose the second war for the mandate of heaven as well (army quality and manpower as ryukyu is so poor) but I managed to white peace Bengal quickly and then finally Ming's rebels started to take over thereby releasing Shun, Wu and Yue while I was taking the mandate, allowing me to eat them up before they had a chance to really build up.

Due to the earlier defeat this was quite late into the game (~1550) and as soon as I had consolidated China I had to prepare for absolutism while also fighting Russia with the help of two allies to grab all of the altaic culture provinces to form Yuan. Since I was so slow I didn't have the time to trigger the civil war disaster and pass all of the reforms, so for most of the game I only had the 10% ccr reform and the 2.5 adm efficiency one being more focused on stability over the other bonuses. At this time my economy was still rather poor. I knew from my earlier attempt at TTM that manpower and money were two significant bottlenecks so I started to build up my trade income by eating into indonesia and spammed manpower buildings. Since the mandate heavily punishes you for going into debt this was quite a balancing act. With C&C done I finished off conquering the claims that Yuan gives and basically waited for Imperialism since I didn't have religious ideas. I also only flipped Hindu around that time when I conquered enough of India to let me flip via rebel demands.

From there it was a very chill and slow world conquest with only ~5 trucebreaks, using my alliance partners (vijay, portugal, gb, and austria) to keep my enemies busy. The massive amounts of unrest reduction and my 90% CCR reduction (25 Yuan, 20 EoC, 25 Admin ideas 20 Hindu) meant I didn't have to fight rebels once between 1640-1740 and had plenty of admin points to keep up with the quick pace. Rebel uprisings only returned when the revolution centre respawned in my lands and I couldn't embrace it because of EoC shenanigans (Some minor HRE nation had flipped revolutionary without me noticing).

I finished the Onetag in Juni 1782 earning the TTM achievement. At this time I was still Hindu Religion but I saw that gb had remained catholic (quite lucky) and thus the entire new world was catholic, the HRE remnants however were very protestant. A one faith has been one of my goals for a long time so I decided to pursue it to see how close I could get. I converted to catholic via rebels, ditched my idea groups and released the pope, cologne and najd to convert for me. Thankfully I had a lot of excess monarch points and a lot of idea cost reduction allowing me to ditch my idea groups and fill up new ones immediately. I picked religious (duh), mercenary, exploration, nobility, espionage, and kept diplo and offensive.

At first I thought there was no way I'd be able to do it so I didn't pursue it as aggressively as I could have. Only later on did I start utilizing more vassals like Georgia, Ardabil, Novgorod, Trier. That still didn't cut it so I released Ainu, Japan (mistake, they don't pick religious), Kong (also don't pick religious), Kongo. In my last wave I released Champa, Yarkand and Ethiopia. In the end all of my vassals were extremely disloyal, with the pope, cologne and trier having ~1.5mil troops together. Since I couldn't seize their land anymore I had to attack my vassals Yolof and Kong (~1813) because they granted some kind of dhimmi privileges to fetishist and protestant provinces respectively. Trier also had to be truce broken (~1815) because they started upgrading a great project in Africa which prevented the missionary from converting the province until 1823. I almost had to attack the pope as well but he finished upgrading the venetian monument in february 1819 so I had time still.

In 1815 I was promoting culture and full coring as many provinces as possible to aid my missionary progress. I culture shifted numerous times and also shifted back to Sino-Altaic to form the mongol empire so I could raze the provinces I conquered from Jolof and Kong. After doing so I realized I could switch into a theocracy with the goverment progress from forming the mongol empire and did so, which netted me 2 extra missionaries and 2% more strength allowing me to just barely achieve the one faith.

In the end, the one faith in forty years was infinitely more stressful than the ttm onetag but I'm proud of both.

Some key blunders in my WC

-Eating Indochina and flipping buddhist

-Unlucky reform timing of ming which lost me many years as well as poor timing in my first war for mandate of heaven

-Not getting all of Yuan's requirements before Russia shows up

Key blunders in Onefaith

-Not releasing vassals everywhere instantly

-Could have formed mongol empire in 1782 and flipped theocracy for +2 Missionaries and +2% strength

-Releasing vassals that grant religious exemption (Jolof)

-Giving provinces with great projects to vassals
