*Wall'o'text approaching, you have been warned*
I enjoyed this game very much and also thought it was one of the best I've played (my first emperor win too

)
I decided I didn't want too many cites, but wanted massive ones so I went down the tradition track. By the end of my demographic on population was 35,701,000 while the world average was ~17,000,000. Athens finished with a population of 29 and sparta not far behind at 27.
Early on I waited until getting the NC before settling my next cities. I was also able to get the Great Library. While preparing hopolites to assault Rome Persia asked me declare war with them. I took and puppeted the Roman city of Antitum (settled north of rome) while Persia captured Rome. Rome was eliminated and peace remaned on our continent for many turns as I build up infastructure. One very important construction during this time was completing the Porcelein tower in sparta. Now I had two cities getting GS at a fair rate.
Once I discovered rifling I upgraded all my musketmen and attack Persia, taking Rome and a persia city south of it. I sued for peace and got some nice GPT as well as 3 mroe puppets (one a razed... I thought it was a different city but the actual city turned out to be worthless.)
With the money from persia and income boost from 4 new puppets my science began to get a huge boost. This was also thanks to the rationalism tree and the Partronage policy allowing CS to contribute science.
Eventually another war broke out with persia and I took their capital, leaving them with just three cities. The ottomans declared war on me once I started building spaceship parts, and even nuked Persepolis! (which I am actually angry about becaues the game gave
NO notification of this. I had no idea it had happened until I had noticed the fallout 2 turns later

is my city being nuked not pop up worthy?) But by this point it was too late to stop me anyway, but to punish them I puppetted the two cities they had settled on my continent.
By the time I won ( and many turns before ) I was generating 1638

each turn. About 350 or 400 was from CS allies, and Athens was producing 304.5. I dont have exact numbers but sparta wasn't far behind, probably around 270.
So if I learned one thing from this game, it is that I now love the tradition branch

I look foward to participating in many more GOTM.
