Hi first time posting here.
I completed a space victory by 1948 with the conditions imposed. It was my first time beating the game on King difficulty and also first time playing archipelago. It was quite a memorable game, and it was insanely long as well
I spawned on a location with many gold tiles, room for about one more city and also next to Oslo, a maritime CS. I rushed to civil service with GL in this game, although I didn't have many rivers to take full advantage of this tech, the medieval era let me spend my saved up culture points on the patronage tree. I immediately became allies with oslo after, and never let it drop.
After that, I got the tech that would allow me to scout around my surrounding area. I found the various civs and city states and befriended all of the maritime ones, and eventually the cultural ones too as I got a science bonus from allied states with a tech in patronage tree.
I had two cities on my spawning island, Washington and New York and made a third one - Boston - on the island to my west which was only occupied by another maritime state. Right when I was moving my settler to get a fourth city on this western island, Montezuma made Calixtlahuaca in the exact same place I had planned to put my own city! After that, I declared war and captured the city as it was in my sphere of influence
After this little engagement, and favorable settlement terms for me I rarely made any units at all. I kept on refusing open border treaties with other civs which I guess is what caused my approval rating to be the lowest at the end of the game. Instead after the appropriate tech I made about 4 destroyers to control key points of the map. I honestly didn't need them but it felt good to know that no civ was ever going to walk on my lands with any ease at all. I also made a submarine and a carrier with a B17
After discovering I had no coal nearby any of my 4 cities I decided to found another city - Philadelphia very far away from my own civ but did provide a nice coal tile. I only had one destroyer defending this the whole game. This city turned to be a growth and production powerhouse later on, and also added nice beaker bonuses.
My social policies were: Full patronage tree, followed by commerce up to +3 production in all coastal cities and then order up to communism ( +5 production ).
As for my tech I went this route: I got satellites first, followed by robotics and then completing the route that leads to globalization which gave me access to particle physics and nanotechnology. So I built in this order: Apollo program as soon as I got rocketry, SS Cockpit with Satelites, then Spaceship factory in 3 cities and 3 SS Booster in those 3 cities while I researched the globalization line of tech. Once I got particle physics I had saved a great scientist to get nanotech at the same time and afterward immediately began production of the other two necessary items.
The end populations were Washington 22, NY 13, Boston 20, Calixtlahuaca 12 and Philadelphia 15.
What I could have done different?
Maybe my tech route was inefficient. The boost you get from research labs is pretty big and perhaps it would've been more beneficial to get this tech first. I haven't played many civ games prior to this one, and I was still confused on how specialist works, but this game I think I got a hang of it. I wasn't using specialists efficiently all throughout the game but at the end I had a good allocation of different specialists throughout my cities. Maybe I could've done this faster paying proper attention to this. Also, I would consider building significantly less units as cities could be focused on research instead and the other civs never seem to attack if I do not open my borders to them.
As for social policies, I'm thinking now rationalism could be a great policy to experiment with as the +2 free techs is awesome, but at the time I was more worried with production and how fast I would build the space ship parts as my beaker production was pretty good (196 beakers for Washington alone at the end of the game).
Also, throughout the game I must've gotten 4 great scientist who I didn't use to discover a tech but instead founded academies near Washington. Does anyone know if this is more or less cost efficient than otherwise? I haven't done the calculations, but I imagine if you get a scientist earlier in the game it is best to settle him down to an academy and get the benefits throughout the game.
It was a fun game and I am looking forward to the next challenge. But do not do epic speed again! It felt unnecessarily slow.
