Im not that type, but i just rage-quited from my polish game
...
There was a discussion about the polish UP that how awesome it is. No its not. only theoretically. They cant build all that buildings, especial in all your cities.
Personally I am on the side that the Polish UP as it is right now is not that awesome.
But when you take the arguments from the opponents side into consideration you can prevent yourself from rage quitting an additional time.
The fun in the game is through expression.
Now expression is a very personal thing.
Some people like to express themselves as a bird.
And some people like to express damn elves! as an elephant.
Generally the expression of a bird and an elephant are mutually exclusive.
The Polish UP supports both expressions so it is a very good UP.
That the simultaneous persuasion of both the bird and the elephant leads to ruin is due to a fault that lies with the player not with the UP.
Judging from your post you fell prey to the fault of wanting too much too soon. (You did not have enough production to support the armysize you desired.)
My personal opinion is that this is exactly the mistake the Polish UP encourages and that therefore the Polish UP is a very beginner unfriendly UP. Even players the caliber as yourself (Gilgames) apparently occasionally fall prey to it. And with the amount of emperor victories under your belt you are hard to consider as a beginner. That makes the Polish UP at least partially a handicap in my book.
Now there is no actual urgent need to fix anything broken with the UP of Poland. But personally I do feel that taking away some of the expression of either side and adding it to the other side will make the experience more enjoyable over all. (current experience for playing two polish games with two very different expressions: 'bird'~8 and 'elephant'~7. Proposed experience:
either 'bird'~7 and 'elephant'~9
or 'bird'~10 and 'elephant'~6)
Having said that. A succesfull Polish game probably needs a solution similar to the recipe of victory for the first French UHV-condition.
Note how the solution to the French first UHV-condition (location of initial cities and priority of improvement and defence of tiles) is unrelated to their UP in its current form. (theoretically the city of Hoff, with acces to both copper and iron in Saxony, is a little better and would benefit from the French UP. But its additional production is negated and countered by the additional barbarian pressure.
If only there was an additional village one plot southeast of Paris to allow a spot with more commerce so the need to spawn barbarians through pillage for money was reduced...)
With your record on the first French UHV I have full confidence that you (Gilgames) will find the solution to the three Polish UHV-conditions eventually.
And since my prediction of the Polish UP turning out to be not so great for future attemptees turned out to be correct let me make another one:
When you eventually do find the solution your victory will be all the sweeter.
