Science Victory, T171 Score 1577
Plan
I did not know the leader (never played), but I did played china a bit therefore for a science victory I focus on eureka, this time I decided to grab as many land as I can because from previous gotm AAR I found this is where I need to improve...
Because of the Start location and the amount of floodplain and marsh I decided that my top priority was to rush Etemenanki wonder... Then because of China special eureka on wonders I had in mind to go for as many wonders as possible as quickly as possible; so to get a good balance on conquering neighbor, building wonders I decided to focus on 3-4 good cities first and then develop my empire
Early game
Etemenanki was my first priority I explored my river first to get the best location for it..First I decided to not rush for an early war with Qin but whenever I see an opportunity for a quick victory I will go for it...
Decided my B2 will be south east from me, because it will be my stronger early B2 before I got any bonuses (2-2 title + 2x sugar)
I decided the best location for Etemenanki will be my B3 south west from my capital.
I settled my B4 coastal on south with very good early bonuses (Etemenanki + pantheon)
By turn 85 I only got 4 cities
Conquest
I first conquered Qin (T82-105)
waiting for caravel (noticed very early his capital was coastal but he built wall very early... too early for a galley rush) + 2 catapult/2 horses/3 archers ... I had no iron in the early game so horses was the only strategic resource available. (which actual was decisive for the end game)
Then I went for Vietnam with 1 fregate 3 coursers, supported by my trebuchet/crossbow (T110-120)
Then I came for Samarkand which opened to mongol land : serious business started here as I took an emergency to save Indonesia ( totally killed by Mongol T115)
right after Samarkand complete pillage I upgraded my level 2 coursers as cavalry and I founded my economy based on full pillage of Mongolia (built a couple more of coursers/cavalry) then capturing his best cities
Regarding the others ones : I revived Indonesia for nice favor boost + had no interest in the city...
I kept 3 strong cities (with nice chops available for space project in the end game), let 1 city turned as a free city and razed the last 2 ones in the end as he declined any peace treaty with me
Finally I stop conquered any cities, as I was letting other AI's survived... However my lvl2/3 cavalry get upgraded to Helicopter T150 and unfortunately for them all other's AI decided to go in emergency against me as I conquered Mongol capital at the same time...
Therefore just by T175 all district/mines/improvement in the map get pillaged. In the end game my income reached 3000-5000 gold per turn and 1000-2000 faith per turn
I had a lot of fun doing this... I also managed to time a x6-7 campus pillage in a single turn with wonder scientist to one turn the last science as I was stacking prod/prepare chop in all my cities to start mass space project in all my space port to save 1 turn
Note sure if my decision to stop conquering city was a good one, but at this stage I decided to focus on +3/5 amenities bonus to boost their production outcome, having more cities would have boost my science eventually by a bit but would have cost me some turn lost in completing some space project
Cities
21 cities, settled 6 only, all others were conquered.
I had in mind to focus on few cities first to rush wonder + Qin box me very early in my expansion; therefore Ancestral Hall was not an option for me in this game (even if I value this one a lot)
I decided to go with Audience Chamber as I wanted to focus on leader bonus to rush city with 10 pop (for science and culture bonus) and also I always value a lot amenities so Audience helped me a lot to get a reliable +3/+5 bonus asap
but I believe Throne is a strong alternative having +20% prod bonus from turn 80 to the end in my game would have been fantastic too... I am wondering what would have been my game here... on the other hand I would have loose a lot of turn and energy to rush for 10 pop cities in my early game...
This 10pop bonus was a turning point to get science lead early over the AI's... Actually I did some food project on my cities to either get to a new district cap (mostly on my conquered ones) but I did it in the one I founded to go from 8-9 to 10 pop (especially with the one I founded because they had a lot of production)
Qin cities were actually quite bad: they only purposed was to get to 10 pop more or less...
Vietnam cities were quite good
Mongol cities help me to get 2 spot for buying/chopping space project (with moksha4/magnus )
Governors
I opened Pingala first for science/culture boost in my capital (also for the space project boost as I identified early my cap as best production outcome thanks to a nice industrial zone + ruhr potential with all those nice hill).
Note I realized I did not faced the bug with dam as the only one I planned get denied by salpeter in my capital...
then I went for Magnus 2 (to boost growth in my B2 combined with sugar corporation) and to set internal road to my b2 (+4/5 food +2/3prod was a nice boost to all other cities)
other governor were used for the Audience boost, I also used Victor to rotate in some cities to get housing bonuses and help them to rush to 10pop
I set a moksha 4 followed by magnus in the end game to buy/rush last space project in one of the mongol city I conquered (this city was founded by Indonesia initially)
Diplomacy
None: war, war, war!!!
get few luxury ressource deals not sell any favor nor strategic resources (I missed a lot of strategic in the early)
Technology and Civics
I tried to get as many Eureka as possible supported by 2 free inquiry area
initially rushed first empire (hard tech foreign trade) then classic republic then recorded history (campus boost) then feudalism
Regarding tech: pottery, writing (Etemenanky rush+ 3x campus opening), irrigation (to work my luxury), Currency(corporation boost/internal road), masonry (pyramid), Apprenticeship, Cartography, Industrialization was my priority order
Religion
Pantheon Lady of the Reeds and Marshes: as a BBG player I initially planned for the broken pantheon giving a free settler but I noticed +2 prod on all those tiles was too good to pass on (from +1 prod in BBG)
Religion none... I was thinking about a late religion to use my faith to buy campus building and/or extra amenities when I noticed Stonehenge was still opened... but when I decided to go with stonehenge last religion get completed the next turn... it was a bit annoying to get this tile occupy by my unfinished stonehenge for the rest of the game in my b3 (spent 1 turn in it and unfortunately this is the first game were AI did not built Stonehenge at all, so I had to live with this unfinished job)
Wonders
Etemenanki in my B3 T63 was the turning point to sky rocket in yields/science: the main focus since turn1
I also completed pyramid T62 in my capital (despite launching it much later)
Artemis in my B2 T67 (found a great place to do it thank to Samarkand camp next to me... I did not really planned to do it but I decided to go all-in with it when I see this opportunity because it was a very nice synergy with Magnus 2 in my B2)
Hanging Garden T91 (B1) nice synergy with leader bonus
Coliseum T128 (B4) loving this wonder a very nice spot for it in my B4
Kilwa T129 (B3) and Halicarnass T134 (B4) were in my to do list for science victory
Forbiden City T134 (B2) thank to great engineer nice to have, found a good opportunity not really planned for it
Rurh valley T136 (B1) love this one whenever I can go for it!
Casa de Contratacion T154 (B1) thanks to engineer between space project turn... I did it because of a mistake on governor title calculation (for my late plan on moshka 4... actually I did not needed to do this wonder at all, but it was close and much convenient with this one)
Note I got an early relic in a hut, and because of wonder spam + high pop in my cities I realized I almost win a cultural victory around T100, when I noticed I immediately gave it to the second in tourism to avoid a cutural victory was in 16/26 from 0/24 in a couple of turns (I remember someone lose previous gotm because of this so I checked luckily from time to time)
Leader and Civ bonuses
Free inquiry for the first 2 golden age + Civ bonuses = High focus on Eureka all along the game (wonders spam helped me a bit)
I did some food project to get 10 pop cap on 8-9 pop cities to rush the last turns to get the bonus, I set a magnus 2 to set internal road to my B2 to focus on my cities growth
whenever a cities got 10 pop I used victor to rotate between my cities thanks to Audience Chamber, my commercial road was mainly used to boost B1-B3-B4 production to B2 the remaining one to boost other cities growth (did a bit of trader rotation for the other ones)
City States
Used my first trader to Muscat to complete my first quest and secure early suz (my first cities got all commercial hub + secure a golden age)
Zanzibar was also in my back pocket, same as Buenos aires (but this one get destroyed early by barbarians quite early)
I also secured Hong Kong early for my late game (not sure if it boost food project?)
I discovered science CS very late in my game I sent Amani Secured one the other one were too far away to get discovered/contest by AIs
I also secured all the production CS by the end game
Kilwa + Globalization card were decisive for my late game science boost
note: I suzed Vatican T169 did not used this one at all... I thought about conquering this one but did never bother actually
Barbarians
No problem with them, I discovered barbarian clan mode in this game, wondering if everyone get the same CS created along the game? maybe a game with more than 3 blue CS would have helped a lot
Also I did not played with it on purpose... when I had a camp next to me I destroyed it, not sure how to use this game mode efficiently
Corporation game mode
First time playing this mode... I only planned to use sugar corporation to help city growth in my B2 one of the main reason for my B2 placment
cotton in my cap to boost my yield/production in my cap for the late game, bonus on unit was almost useless except for 2/3 horse/courser I casually 1-2 turns them to lunch my wars... Maybe I under estimate a bit how useful it was to boost catapult x2 I built in the early (as there is no policy card to boost siege unit in vanilla game) so cotton corporation boost was the only one available to build my initial army
latter I used another one to boost my science in my B6 (and last city I found in upper left corner mainly to benefit from this corporation... not sure how it boost my overall science
I did used some great trader to improve in monopoly whenever it was feasible to improve yield in my cities
did not used products at any point... not sure how to use it efficiently...

Final state
I had a lot of fun with the map, I personally did not experienced any bug with dam as I did not used any.... I initially planned one for my cap, but it was denied by Saltpeter (I needed to discover this resources for frigate support)
I usually stop on 8-12/13 cities in case I don't go for domination victory... but thanks to gotm I tried to get more land so ending with 21 cities which is like a new record to me in science victory...
I also gain few turns on my previous gotm going for science victory from 175 with Mathias to 171 with this one... with a complete different approach so I really enjoyed this game!
Usually playing BBG space race seems wonky a bit in vanilla rule set (especially the builder boost)... I launch last project T161 first boost from T164 and completed T171 whereas I was traveling at 28years speed per turn in the end... I suspect there was some bug or some mechanic I don't know with power shortage and space project... because I got some red electricity flag close to city name from time to time despite not having any notification like an usual electricity shortage... which was very weird to me because I had enough coal/resources (180+) to feed all my power plants by a large margin...
Closing words
special thanks to
@Rutseg for the AAR formating I had great time reading his last AAR so I used his formatting to do my recap
