Domination victory T200.
I played a Dutch Deity domination game some time ago, and remember being very impressed with the sea beggars, so for this game I went for the sea beggar route again. Tech path was more or less: civil service, workshops, universities, steel, navigation. Combined with the already slow-ish start to the game, this meant I did not hit navigation until turn 153. At that point I had a handful of galleas, and 3200 gold to buy sea beggars (no commerce yet, I had gone exploration instead).
Until this point I had played peacefully, except I had to defend from Elizabeth who attacked me out of nowhere. Thankfully, she sent most of her troops to Geneva instead of to Groningen which was somewhat vulnerable. After I upgraded my galleas and bought some sea beggars, I was only too happy to set sail for London as Elizabeth had built Temple of Artemis, Chichen Itza, Machu Picchu, and Notre Dame there.
After that, I let myself be distracted building useless infrastructure (windmills, factories, banks), instead of pumping units from all cities. Only the heroic epic capital kept building sea beggars most of the time. All that infrastructure could then be used to choose Autocracy for cheaper unit purchasing, combined with Commerce and Big Ben. I achieved this around turn 180, when I had around 5000 gold in the bank to spend on units (sea beggar: 260 gold, frigate 300). Too late to be impactful, but still fun. I can see how this might be powerful in multi-player, if you can immediately buy, for instance, stacks of bombers, but in single player it's often possible to build an army much earlier.
I had fun this game with the sea beggars, but they were not as good as I remembered. After slamming a city twice, the ship would typically be at 40-50% health. The cities also take a lot of damage (and the gold from coastal raider is cute), but I needed a bigger fleet of sea beggars to really take a city quickly. As it was, my frigates still did quite a lot of the heavy lifting (when adapting the map, I might have ensured a bit more iron to be available though).
Below: my unnecessarily large cities, but first: the AI can't take a hint. When making the map, a point of discussion was the lack of easy-to-reach islands for Indonesia. So, I had made sure two islands to the east would be reachable after optics, and added a bunch of fish to ensure the cities would be worth conquering later on. What did Indonesia settle instead? A one-tile island to the west with a single (shared) sea resource.
