I settled in place because I wanted to work the fish early and I also wanted to try the Glighthouse. I ended up wonder spamming heavily in the BC years as I had my first two cities (Paris and Orleans) building lots of wonders. Paris got the GL, GLH, Sistine, Pentagon, and UoS. Orleans got the Mids, Parthenon, Ankor, Taj, GW, and MoM. The GLH was very powerful on this map - it easily propelled me to the tech lead until the AI's started to adopt mercantilism.
Unfortunately, because of all the wonder spamming Shaka came after me more than once. The first time, I luckily had metal casting so I built triremes to bust up his galleys before he could land troops on my land. The second time he attacked me, I was setting up for a steel slingshot from liberalism. This time he managed to land a few troops but I began my double MoM enhanced GA spree (2 GP + Taj). I built up a modest stack of musketeers
and cannons. I then shipped them over in galleys to Shaka's lands and started to take one city after another. Since he didn't have curaissers until the very end of the war, he couldn't kill my cannons (no flank attack!). I was quite impressed with the steel sling - I may do this more in my future games as it appears to be more powerful than the rifling sling if you have the production to abuse it.
I took about half of Shaka's lands before I decided to take peace. I was worried that he would vassalize to somebody else and drag me into a protracted war - something I did not want to do at this point as I had other fish to fry. Notably, Asoka had settled very close to me and even managed to get a city on the eastern edge (I was lazy settling). Since Asoka was in the lead, I decided to whittle him down next. Unfortuately it took a VERY long time to get my boats over so I only had enough time to take a few cities (rifles/cannons at this point) before he got up to rifles. I took peace after that and regrouped for a while.
At this point, I basically hunkered down to get factories up and running in my cities to begin my late game push. Unfortuantely Joao (who had been swapping in and out of vassalage to Asoka) declared on me for no reason. I had more power than him so I wasn't quite sure what he was up to - particularly since he didn't even have an invasion stack coming after me. I had managed to get up to combustion/industrialism around this point so I sent out the marines to take Joao's island holdings. Unfortunately he vassaled back to Asoka and dragged me into another war
I didn't war with Asoka very long the second time as Shaka bizarrely (or in character) attacked me again. This time I beat him back badly (tanks own rifles) and reduced him to one island city. Unfortunately the city was on the other side of the map so I just capitulated him. I then regrouped my troops to build up a modern navy and set forth on Asoka again.
Asoka didn't have much of a military so he only put up token resistance. I lost most of my units attacking the 1 tile island cities - his continental holdings fell very quickly to tanks (and later mech infantry/modern armor). Around this time, I also got the internet and turned off research. I basically just built air force + mech infantry for the rest of the game. I commenced my chain of vassalizing with Asoka, Joao, followed by Cyrus.
Justinian and Brennus were at war and Brennus was losing horribly so I used the UN to broker peace. I then sent my stack to Justinian's capital as his sod was stuck near Brennus's lands without transports. I commenced my landing campaign from the east and was cruising along. But I got tired and just took the diplo win via vassals
A very late win:
good for about 60k.
Here's the power graph - you can see where I declared war on Justinian
The GNP (although my research was internet fueled for the last 50 turns of the game or so):
The big spike around 1760 is where I bit the bullet and took a 2 turn anarchy to shift into police state. I stayed in police state for the rest of the game since I figured I'd be warring the rest of the way out.
And the backbone of my victory, production:
I was able to get 4 really good production cities. 3 on my starting island and 1 from Shaka. All 4 had around 50 base hammers + factory, forge, power, military academy for a total of 100%? These 4 cities were cranking out mech. infantry every 2 turns so I had around 70 at the end of the game. Too bad the AI doesn't know how to kill mech infantry...
This game proved to be quite an annoying map with all the islands. Many of the AI were able to tech fairly well in the late game because they were all getting inter-continental trade routes from all the minor colonies on the islands. As a result, Asoka and Justinian (and later Cyrus) were all able to tech pretty well. I had a tech lead for about 2/3 of the game at which point Justinian and Asoka started to pull away a bit. I took down Asoka easily but I only caught up to Justinian after I got the internet.
I only have the Empire Overview shot in 925bc, sorry.}
move. I should have gone worker first.
The first turn of the war Shaka suicides six units amphibiously, we loose a sword.
I was tech trading with Asoka and he was probably gaining the benefit from trading with the others I hadn't met.
