A few things to keep in mind: As always the units are work in progress, some other units are still in the making and will be added at a later point.
Playable factions are Lesser Poland and Silesia, though nothing is set in stone.
Enjoy 
Excellent as always!!!
So AWSOME!
Awesome, but as I remember from my history lessons the unification of Poland in the early XIV century by Władysław I the Elbow-high started from Kuyavia (or however it is spelled in English XD). This region is located around southern tip of the Gothiscandza, wich in your mod is occupied by Pomerania by what I see from the map.
Thus, my proposal is, can we please have Pomerania playable? It's historicaly accurate I believe. And I get that Pomerania was conquered like 100 years later by Teutons, and it's not like Pomerania=Kuyavia, but this roster is so much cooler than the other ones :3
Its so awesome to see poland! Thank you very much for this faction :)
Getting excited for this mod. Keep up the excellent work! I do have one question: will all factions, even ones that will be unplayable in the campaign, be playable in custom battles?
I've just noticed the officer of the High Polish Knights of Lesser/Greater Poland.. he has the same coat of arms as this guy En.wikipedia.org, and a bit darker armour too. Nice easter egg!
POLAND STRONK RUSSIA WE WAR YOU!!!1!!!TWO!!1!!11
DOPE
The Kingdom of Redania, good to see it! Radovid would be proud.
Looks amazing :)
GOOD WORK

looks very very promissiong althought i would love to see very very characteristic units in polish roster such as "husaria" also idk if that's even slightly possible but as you may or may not know "husaria" used difrent tactics in comparison to all of the other european cav as they where sticking close to each other in charge witch made them look more scary,big etc. and vas very evective in charging (also they had slightly bigger horses than other countries coz of special breed). i would be very pleased and happy if implemmenting that would be possible
dude husaria as the oryginal heavy cav was in end of XVI century, at the beginning of that century it was light cav for egzample battle of orsza. so it's not that period of time whats more they didn't have any special breed of horses they just bought the best horses on market which had special skills they were looking for. there was no such a thing as Hussars horse - special breed... read a litle bit...
are u going to make more polish units? for example two handed sword, maces long short - two handed one handed morning stars in Poland we call them cep bojowy (many kinds). They were often using czech mercenary heavy infantry with really big blunt weapons.And one thing more every one agree that polish tradition is cav but to be honest they are not the best in game...u gave some unique infantry units to other countries but Poland hasvery good cav but not the best i think they should have one...
