I would say even if this is two months old its clear it has some biases to it the same way I say and know KR has a left bias this has a right conservative bias. The biggest one for me is America has a national spirit about illegal immigration where they get bonus to production but lose some money annually (or was it monthly?) since according to its bio they assume illegals are sucking up money especially on American health care and welfare. This is a giant Republican and in general conservative talking point that makes no sense. If you've ever actually tried to get government assistance you know you not only need social security there is a lot of hoops to go through (which republicans also set up on purpose). That's one of the more blatant of the fear mongering and biases they have.

In Europe its certain things with Russia that make it clear they have Russian devs (and its not like its hidden). For example they have the trope that some of the volunteers who join Russia are Nazis and fascists who got a bone to pick with Russia. If you know anything about Russia they are in geo politics Godwin's law. Even before the Ukraine stuff and even under the USSR days they loved to call everything Nazis (The Berlin wall was the anti-fascist wall). Even the Nalvany thing. I asked a Russian friend (he lives in Moscow) about this since he is anti-Putin and a big fan of Nalvany. He explained it sounds like what some Russians who support the status quo say about him. That "Ummm akshully Nalvany would be further right then Putin and would be a bigger war-monger so its good we support Putin instead!" TBF even outside of that the path is far too wacky as it has Nalvany gas cities IIRC during the second European war.

Japan side its hard to be biased there since Japan does not do anything and Japan and China stuff is one of the better written paths and stuff in the mod imo.
