So, I'm in 1778, and have conquered my continent, nearly all of the second continent, and am starting on the third landmass (with Germany and Russia), thinking, "man, I ought to be about 2 tiles from domination". Fired up CAII, and it says there are 1341 land tiles, with a domination limit of 1315; I have 1122 domination tiles (roughly 85% of the domination limit), and 83% of the world's citizenry.
Is something unusual going on with the domination limit? I see @Più Freddo
mentioned reaching presumably just shy of the domination limit, and then going for 20K. In Conquests I'd just check the F8 status, but since it's PTW, CAII is the only option... and I'm wondering if its reporting is off, or if the limit's 98%.
Aside from that, it's been a good game. After my early wars, I stayed peaceful for awhile, building too many forts to brush back an expected strong Roman attack after war started, only to find they were weaker than expected. Swords and MDI fought them on land while a north coast based Berserker force provided crucial marine strength to win the war, spanning about 1000 AD to 1230 AD. Berserkers featured prominently against Egypt, as well, which was an easier conflict, spanning 1340 to 1385.
At that point, we were in the late Middle Ages and backwards, so I decided to bring the AI into wars against each other to slow their Republics down to my Monarchy pace. I declared war on France and England, bringing in the Celts against France and Spain against England, and started attacking France with Berserks in a raider style. We'd take a city, and before they could launch much of a counter-attack, would load back up onto a boat. Soon, we'd start leaving some Pikemen in the cities as they were available. This worked effectively to whittle down France's strength, and by about 1500 we'd taken most of their land. But they got Riflemen in Paris and Marseilles, which proved a tough nut for our Berserkers to crack, so we spent about a century building up strength and sieging the two cities, finally conquering France in 1620.
By this point Arabia had been brought in to wars as well, against both France and the Celts. I'd also realized that Spain was beating up England too much, and switched sides to propping up England, sending coals to Newcastle and various spare luxuries to Canterbury in an effort to keep the English economy afloat until meaningful numbers of Viking troops could arrive.
The AI wars had also had their intended effect, and in the span of 250 years, I had gone from backwards to advanced, being the only industrialized nation. This lead to a great increase in productivity, and what was at first a small amount of troops crossing the Arabian desert to fight Spain quickly swelled. By 1700 we'd cut a line across Spain that protected England from most of their troops, and by 1754 Spain was effectively toast, and we'd attacked Arabia as well, as they had grown too powerful by conquering all but one Celtic city.
Now, in 1778, we have conquered Arabia, taken the last Celtic city to avoid flips, have taken all original Spanish cities, and have invaded Russia, with Germany also at war with us though a lower priority as the only civ still in the Middle Ages. England our one ally, and at their own suggestion has a mutual protection pact with us. We've completed Hoover Dam and will have Combustion in two turns. Probably going to go for Domination or Conquest.
