Well... I didn't horseman rush this time. It worked well in the last game, but this time I wanted to try something different. I played with 2 cities and went for early renaissance with my first 2 great scientists on education and acoustics. The reason for this was to get the full rationalism tree as early as possible, and only expand afterwards.
I didn't want to risk any early wonders, so I went for the stonehenge + oracle combo, because that seemed to be the sure thing. While I was waiting for the second GS, I almost finished slowteching chivalry. By the time I got the GS, thx to my wonders, I had enough culture to unlock everything in rationalism, although I waited with the extra techs till I had something expensive to spend them on.
This seemed like a slow start, but as it turns out I either managed to turn it around, or it wasn't as slow as it seemed. With the trading post and specialist science bonuses and those early universities in my first 2 cities, my research wasn't bad at all, and at this point I started expanding. I made 2 settlers, settled the horses, and as soon as I got chivalry I made/bought 4 knights. It was early enough to kill everyone on my continent with just those knights. Liz had longbows, but I bribed her to go to war against Ghandi right before I declared on her, so her forces were divided.
I didn't go to the other continent (only with a caravel to explore), I used the 3 AIs there for research agreements. Instead I stabilized my home continent, eventually I made some more settlers to fill in the gaps. I went for the forbidden palace + planned economy combo, plus given the great UU, my happiness was better than in many of my other games. I obviously teched towards science buildings, and after plastics I went for the apollo program. I chose order for my secondary policy tree, and managed to get communism while building the apollo program. I made my 4 initial cities mostly hammer cities (while they were capable running scientists too, which they were doing heavily till I started to build the spaceship parts), and I annexed Paris early, and built up a nice fifth production city there. Trading post spam everywhere else. Eventually not everything turned out perfect, because I had to wait 5 turns for the last booster from Paris. I should have built railroads all the way, or at least I should have bought the spaceship factory earlier there.
But overall I'm satisfied with myself
