The sheer luck they had going for them is something that cant be replicated.
Nations had excellent and awful luck through history, Ottomans probably weren't the "luckiest" overall, but that's hard to measure anyway. The assertion that you can't replicate it in-game with literally any nation in the world, however, is disingenuous. People can do 1-tag WC in the game, by design, yet you can't replicate Ottoman history/luck?
To claim someone could do the same is like claiming poland could take on the third reich and after launch an identical invasion of france in WW2.
In the scenario I described above (which you are routinely and very notably ignoring outright), I detailed scenarios where this had already effectively happened (IE Kazan already holds Danzig, or Aq Qoyunlu holds Vienna). It's not a matter of whether they can do it. In that world, it's already happened. They're larger and luckier than our history's Ottomans, accomplishing something that this world's Ottomans didn't do. You are repeatedly choosing to ignore that. Why?
How would Aq Qoyunlu possibly get into europe to begin with or keep it for that matter?
100% irrelevant. If you're addressing my posts address them. The game allows it. The player has done it already, owning all of the Balkans, Egypt, and half the PLC along with Vienna. Europe hasn't stopped them, and their unrest/separatism is non-existent in Vienna.
Why can't they "western focus"? You're trying to tell me it's impossible, which is a non-sequitur, irrelevant red herring. Obviously, in that world they've done it. Tell me why, given that scenario, they can't do what the Ottomans can do in that scenario. While you're at it, feel free to explain why Circassia and Theodoro can similarly hold that territory and freebiewesternize, but not Aq Qoyunlu or Shirvan, holding the same territory with the same accomplishments.
I posit the reason you are focusing on the impossibility of an already-done task is that you can't and/or don't want to try to address the point I made, that a nation that *has*, in fact, *already* out-done the Ottomans can't take the decision and that there is no rational basis whereby the "western focus" decision exists at all that they can't do so.
Hindsight bias is not a legitimate answer, and neither is denying the possibility of something you can obviously do in the game. What is the answer?
