Ran the back-to-back GAs which fit perfectly together and reached State Property on T210, 1500AD. Teched my way to Flight and Infantry peacefully. There wound up being a 3rd GA in 1650AD because I couldn't help myself.
I prebuilt my navy of Galleons and Frigates to upgrade when the time came so I could concentrate on Carriers and Planes once I hit flight (1675AD).
I know this is not usually wise...but I actually skipped rifling intentionally and let Peter get it for me, traded for it 3 turns after I got flight.
Started teching towards tanks once I had fighters, reached Industrialism 3 turns after my short war with Zara.
War started 1755AD, ended 1785AD. Upgraded most of my Frigates>Destroyers but didn't bother with the Galleons. Had 12 full carriers of fighters and just went down the east coast, bombard with destroyers, bomb with fighters, kill units with CR3 Amphibious Infantry from the boats. I took only 1 city at the start that I could defend with guys from the mainland, kept leaving 1 guy in the other cities and moving on so I didn't have to leave my boats (and my Woodsman3 Medic3 GG who was hanging out there with them. When I reached Aksum I took that and Laibela on the same turn without a threat of a counter attack, which allowed for some movement and I could mop up the rest with Cavalry, Cuirs, Knights after hitting them with the planes.
Next up is Wang Kon once I have about 30 tanks to dump in Seoul (should just be a couple of turns, Moscow is 1 turning them and I'm building them in any city with good production). He has planes and infantry, should fall very quickly. His culture is strong, so I will wipe him off of his peninsula. After that we move to Hammurabi who doesn't have oil. I did just stop automating my workers, have a tedious turn coming up next where I will double check that biology isn't going to force any cities to grow into unhappiness, just to practice that.
