I settled, as it turned out, 1E from horses after spotting all the other livestock in the vicinity. Worker, than warriors, then chariot - the first one came right on time to screw off the head pf a barb warrior stomping my horses. Then, moving barb-busting regiments outwards, I was able to settle (very late - turn 74) a city on the east coast at flood plains site, and another in between of it and Moscow. My chariots had problems with axes, but by that time their spawning grounds were decimated.
Send a scouting galley with a farsight chariot - this trick was on from like forever, CFR did in in SGOTM-1, but perhaps Erkon hadn't been here yet

- rather late, when I at last managed to settle the westlands and cork the tundra peninsula. After contacting the Brittish immediately sent a settler for border-popping - switched to castes for a short time to get GS from Novgorod faster than GP in Moscow and also expand boundaries and get trade routes. It cost a penny, but was totally worth it.
Sent a galley, met Gandhi, Musa, Bismark, and later China and France.
Oracled Monarchy - was afraid someone else would grab it, and being short on happiness, decided to use warrior-garrisoning to grow my cities. Went perfectly, but was a payload - e.g. I had 11 warriors in StPete, pop 21. Wanted to attempt a late GLhouse, but was just finishing the regular one when beaten to it (35AD), and Pyrs were built even before Oracle. My only other wonder IIRC was Kremlin with a GE (lost couple of turns to Liz who GE-ed Taj)
After that CoL, CS, traded for Maths, Edu, and onwards to MilTrad with Liber. Started pumping out cossacks while moving to Astro for my fleet. Then onwards towards Communism (state property) and Bio (pop growth). Then some rifles and assembly line.
Great People: early Academy, then settling a GP, a GS, lightbulbing part of Edu, cashing 2 GM in India, GE for Kremlin, even had a GAge to speed cossack production and galleon research.
Military: the action was started only by cossacks (mid-14th century), and as the enemies had walls, I didn't bring any cats, but just rammed through. It started with Germany, which had lbows, swords and elephants. I took three coastal cities, but spread my forces thin and had to wait for another shipload from Mother Russia to gather on Berlin and then rush inland. The German part was the longest - 2 centuries total, mostly due to unlucky rng at the start. After that the process became self-enforcing - old units healing, new arriving, low losses due to technical superiority. I crushed Bismark and triple-assaulted Mali from land and sea, decimating him shortly.
About that time I got all the techs I really needed, so switched off Bureau and turned to HRule, Nat-m (2 happies for barracks and drafting defence in cities of vanquished enemy, relieving my cossacks from garrison duty) - Slavery (Kremlin-powered pop-rushing of happiness in new cities, then switched to Castes when started pop-growing) - State Property - Free Religion. Also drafting in Globe city.
After Musa I attacked Liz and believe she didn't manage to finish her ill-stolen Taj GAge. Then France, which already had pikes, but it was too late, nothing could withstand the experienced hordes, and finally China. Then settling few cities - perhaps, prematurely, as my pop was growing rapidly and territory was continiously celebrating the 20-turn anniversary of entering my domain, but the territory limit was finalyl crossed.
War Weariness was the greatest issue, forcing me to invest up to 50% in culture.
