After Spain fell I produced some artillery and melee units and shipped them to Jakarta. When Attilla conquered Edinburgh and was close to conquering Medan I decided to snatch Medan from his clutches. Then, I placed a citadel to steal his citadel, which made it a lot easier to massacre his units (mostly with artillery) and kill him.
Interestingly (as detailed in another thread), London was killed of by Valetta, and she was listed as "has not built a capital". However, I decided to conquer London anyway as it had a unique lux and it would be a good naval base.
The turn I conquered Gdansk and London I got DOW'ed by Polynesia and Spain. My first instinct was to ragequit, but then I calmed down, fired up civ again, and started a defensive war. Spain had much more units than I (I had neglected a good defense, thinking Spain was taken care of - quite stupid as just a few gattling guns and artillery would probably have been enough) and Madrid swapped hands three times or so, it is now a village of 1. I gained the upper hand though and am about to conquer Barcelona.
Against Polynesia it is less fun, attacking battleships with frigates is not my thing. I did capture a couple ironclads, and managed to sink two batteships with mainly coastal artillery and a range+logistics frigate that sails out the harbour, fires two shots, and sails back in. He sent a couple of fleets, but I haven't really seen much of an army yet. He has bombers though, so every time I come close I get slapped.
I went autocracy (Polynesia went order first, maybe I should have followed for the diplo and happy). Hapiness was easy for a while but is not close to zero again, unfortunately. The spy bonus really helps though, I have three spies on Polynesia, and stole electricity and flight. He is still well ahead of me, but at least I now have an answer to his bombers, and prora should give me a good happy fix for a bit.
My current plan is to catch up a little on tech, at least to electronics, and do a coastal attack on Honolulu while driving my army North against Warsaw as soon as I have AA guns timed with Clausewitz. Backup plan is to get nukes
