But the common people themselves where practicly the same and the two principalities habe been under the authority of same crown for a few centuries by now, I also don't think the two need to have 2 different cultures from gameplay perspective since the cultural names for the locations and people are gonna be the same and when you united the 2 principalities you don't have to convert the other culture.
Kind sir. Me and all my ancestry are from the discussed region. So I'd be more than happy to see mighty Halychyna-Volynia ingame.
But.
Yes, common people were almost the same,
but #1 still from different east Slavic tribes.
but #2 common people's will meant nothing (well almost, viche customs still were present these days there) there, only elite's-nobles-boyars (and some clergy ofc) wishes were taken into account (high middle ages, remember)
but #3 elites of Volodymyr and Halych/Lviv were not united, yet. There are recorded complains of Halych nobility and clashes with Danylo and Lev for them granting fiefs in Halychyna to Volhynian boyars.
Some cultural union for kingdom tier would be enough. OR
Dear
@Paradox hteractive. As you're introducing 2 concepts: pops and regional cultures - can we get a melting pop mechanic, so that pops of regional culture of same culture group, when lived for some time in a single political entity will start blending into common culture with significantly increased speed? Ideally this should be controllable by player, determining the desired level of merging (f.e. yes burgers and clergy will not blend faster, but only Poles can be szchlachta (like it was IR but religion-wise as well) Adding capital distance modifiers (so if Bohemian king gets a province in Saxony, connected to the mainland ofc it will be faster, for Halychyna getting a province in Volhynia will get them assimilated really fast, but getting, let's say near Danube - significantly slower). And adding an ability to choose smth like 'let them become proper Halychians' or 'Were of common Ruthenian origin'. Wouldn't that be most correct way to handle this?
For entities of Commonwealth size, by the middle of the game this should produce smth like almost integrated nobility, having somewhat integrated burgers and having regional peasantry like it was IR for all nations, that stepped onto the doorstep of Spring of Nations.
