Here I am, reporting a late space win - 1994 AD.
I agree, I have left over the domination plans - though every single thing was in place to achieve it. Maybe it's lack of time or the prospect of tedious intercontinental troop movements...
Anyway, in 1870AD I decided to go for space, and give a shot to the corporations.
Regarding civics, I adopted US and Emancipation, in addition to the free speech,market and religion. My eco skyrocketed pretty well, research was in deep black while running at 80%. I priviledged space techs, maintaining my defenses up to date to dissuade every neighour.
I got almost every single late game wonder, with the principal being this one :
I tried to win through diplomatic vote, but failed miserably - they just seem to prefer Willem to me - fortunately Willem missed the win by several votes, otherwise I would look pretty stupid
I founded and spreaded pretty well Corporate Jewellers with HQ in Borsippa. I managed to spread it to almost every AI. It's a nice gold boost, though it comes rather late.
My second corp was more impressive, and allowed me to speed my space ship a little bit - Mining Inc.
Anyway, after my crappy initial events, I got several nice ones. Best of are hereafter (I think it's thanks to Solver

):
Several turns later, as my space ship was almost finished, Willem, JC and Surya declared war on Washi, so I joined for fun. I managed to have several modern armors and decided to get myself a city in America ( I was a little bit annoyed hitting just enter, building up my prod/research and railroading every possible square ), which led me to this picturesque sight:
Next turn, with Seatle being Babylonian, I settled for peace.
Spaceship was sent in turn 404, due in 10 turns.
Here is the empire overview the turn before the arrival:
On the next turn, it was finished.
Score-wise, it isn't very great - 13989 and Abraham Lincoln status, well behind a domination score.
This game was great learning various styles of play. I really appreciated it and hope you did appreciate it too
Thanks Jamesds for organizing this event, and I hope you will gather us for another one (on Monarch maybe

?)
Cheers everyone!
