As a Polish history student I must say that they aren't weird, the're just totally bonkers.So, some of the Polish Focus Trees for the new base game HOI 4 update seem a little... weird. To say the least.
You can do updates the TNO way, adding in-depth internal mechanics which show the complex political, economic and social factors at play in different states
Or you can do it the Paradox way, adding meme paths which butcher a country's history and ignore it's entire potential.
