That's why I say this map is ASB. There's no way Poland can conquer most of Germany without a POD well before 1500. Maybe 1200. And then how the hell does France get that big? That's a problem.
Maybe Poland stays united 1138-1306 instead of shattering into many little pieces. Then, it expands into Germany as Germany fragments. They also fight much more against the Turks as they expand into Europe, leading to the Hungarians (the Poles' ally) dominating much of the Balkans. Then, Britain collapses into civil war and fails to unify for a long time. The French (possibly Breton fishermen) discover the New World around 1500. The French and a united Iberia start colonizing, with the French conquering the Aztecs around 1550 or so and their initial attempt to conquer the Incas fails. The Spanish then step in and conquer the Incas out from under the Frenchies' noses. So then the French and Spanish start fighting each other for control of Western Europe and the New World around, say, 1600. This long series of wars ends around 1700, with a crushing French victory. The French get the New World and Italy, while Spain is left with only Iberia to console them. Then, the French start getting frisky and start to expand into North Africa and India, bogging them down for a while. While they are overstretched, the Spanish, a newly-united Britain, and the rebellious Dutch (did I mention they were conquered by France) all attack France around 1750 or so. There's a big-ass war and it all isn't settled until 1770 or so, with the results as a partial Allied victory, but France isn't nowhere near defeated and will probably come back for round 2 soon enough. In the meantime, a French proxy in India uses the weapons and tactics learned from their French teachers to conquer India and start to expand into the Middle East. Then they start ignoring their French allies and strike out on their own, conquering the French ally of Persia in 1810 or so. This started another war, which was mostly inconclusive, though it did see Russia join in European affairs for the first time, by attacking the Allies' supporter, Poland, on behalf of the French. Another Ally, Sweden, then attacked them and conquered the borders on the map. The war ended around 1820, and now the world is gearing up for round 3.
