Well, if you know me, you probably know me as the runner of LefonRoyale. You also probably know that I'm Polish - not going to hide that it impacts my judgement. But why should you vote for Piłsudski's Poland?
1. Generally good AI flavours that don't guarantee Poland to do good (it isn't the Uruguay AI), but certainly make them a strong contender most of the time.
2. Fun first part of the UA that makes them able to come back even when the odds are against them. Makes for good underdog story while not making them snowball out of control too easily (unlike some other UAs)
3. Second part makes them industrial and financial powerhouse if they manage to survive until Industrialization with a lot of land. That's a big IF for any civ (believe me, any civ, unless they are very OP), but it's only a half of UA and a very nice addition that seems flavourful and visually pleasing.
4. Unique units - Leegionary Uhlan and PZL.23. First is a Cavalry replacement that gets stronger the more techs you research. It ensures you will actually see the unique for a while! It has bonus strength vs Armor units - who wouldn't want to see cavalry charge take down some tanks?! As a bonus, when they do finish off some poor poor unit, they deal area damage! Any kind of AoE is incredible in my opinion, as AI likes spamming units and packing them close together... Do you see the pattern here? Poland gets really strong after they survive for a bunch, and the first part of UA really makes it easier for them to survive, but doesn't guarantee it. Let's move on to the second UU then. PZL.23 is a fighter with more range and which is much stronger against land units. You know where this leads? AI loves bombing cities. LOVES IT. 2 range may not sound like much, but it will often lead to additional city or 2 at 0HP, which can make any conquest faster and easier. AI also sometimes (not as often as it should) uses Fighters and Bombers to bomb some land units, which PZL.23 is pretty good at. Honestly clearly superior airforce can be a boundry between victory and disappointing meatgrinder, I've seen it a bunch of times during the countless games I've ran.
4. Very pleasant colour scheme. I know this is purely subjective, but I hope some of you will agree with me - Polish colour scheme is very nice and looks good ingame.
5. Piłsudski is an interesting historical figure. He is widely liked by both Polish left, right and center. All of them agree that he made some quesitonable decisions, but nobody else could reestablish Polish state as quickly and efficiently as him. Remember that Poland wasn't sovereign for the past 123 years when he got into office. That was a tremendous task in front of him, but he managed to reform Polish society and renew the country. He has been vouching for Polish independence for his whole life before that and was imprisoned in Germany for leading the Polish Legions during WWI. He is hell of a badass, as he took on the Soviet Union... He has some controversies associated with him, but despite them everyone here appraises him. But enough about what he did. LOOK AT THAT MOUSTACHE! 6. To make me happy. All those reasons above pale in comparison with this one! I've vouched heavily for Poland during CBRX voting and LefonRoyale voting. Third time is the charm, isn't it? I'm just joking, honestly - vote for whomever you want. But I'd be really glad if my brief statement really made somebody vote for Piłsudski.

Enough of my rabling, love y'all guys and can't wait for the voting results, even if they're not too good for me :)
