Well done PF, you beat me both in score and launch date.
Spaceship in 1275 AD with ~10900 jasons.
Ancient age very uneventful. RCP 3 + 6, canonical path to Republic. The Persians gobbled up all the wonders with the commercial trait, so no chances to trigger the GA before the advent of conquistadors. Oddly enough, the English were complete dogs, they weren't even capable to settle their southern tip, which got occupied by Aztecs (1 colony), Vikings (1 colony) and Persians (2 colonies). Moreover, the Vikings had built the Great Library in Trondheim, and this gave me the nice advantage of getting some techs for free.
In the early MA i zeroed research and spent money to rush things, then i resumed for Engineering after i saw some AS having Mono and Monarchy. Then, a suicide fleet of mine stumbled upon the Persians. I sold/gifted them to the MA and they got Feudalism! Traded for Republic, got Mono and Monarchy with Feud and went full steam for Engineering, which i could trade to Persia before they made contact with the mainland.
So, two different paths for the AS: Persia would go for the lower branch, while the others, who had Mono and Feud but not Eng, would go for the upper branch. In due time, i would capture the Great Library and gobble up everything for free
Things went as planned. I took over the Aztecs, followed by the Vikings, and in the early AD i got on par up to Education and Gunpowder. Then it was the English turn. A leader finally emerged and i used it to move the capital in the middle of the jungle (which i was already clearing) at the center of a RCP 6. Also, i got my Golden Age as soon as possible with a conquistador victory.
In the early IA i took over the Iroquois and this was the end of my military conquests. Research was fast both in the late MA and in the whole rest of the game, with also a decent help from the AS that i was keeping intact as trading partners and also feeding them with every luxury i could. After the GLib feast, they got me Astronomy and Banking in the MA, Rep Parts and Mass Production in the IA and Rocketry and Synthetic Fibers in the Moderns (not counting the two Persian freebies).
So what went wrong? Well, for first, my policy of keeping India, Arabia and Persia untouched had a downside: the Persians had settled the lower part of England and those two colonies, in spite of corruption, were doing a fair amount of research, so i decided to not touch them either, but this had put my already planned deficit of 60/70 tiles under the domination limit to a number that never went below 130. Secondly, the AS were indeed helpful, but not as much as i hoped for, and the reason was that while India and Arabia were connected, the Arabs and the Iroquois never bothered to connect each other, and nor the Indians nor the Arabs cared about building a harbor. Inexplicably, i didn't think at all about signing a RoP with Arabia and sending a worker on a boat into Arabian lands to road the missing link myself until i was about to finish off the Iroquois. My bad.
Finally, for lack of time, i didn't bother to optimize my corrupted part. Usually, my corrupted cities get at least a marketplace and an aqueduct in order to become size 12+ cities with full happiness. Although they would never produce anything worth it, they play they part in maximizing score. I totally forego that part until very late in the game, and so my final score suffered.
Anyway, it was a fun game, and not at all "too easy". If someone is interested, it can download my final save to see my shameless exploit of the RCP mechanism
A good part of my homeland is virtually uncorrupted, with the RCP 6 around the capital and the RCP 3+6 around the FP city placed at the exact distance to be contiguous without actually overlapping each other.
