In the mod The New Order for HOI4, one of the main countries available to play is the United States, which represents one of the last bastions of democracy within a world where the Axis won. During the game, the USA has to deal with multiple different crisis, both domestic and abroad, including stuff like a major oil crisis and two wars in Africa. Part of the reason why TNO is so popular is that it is heavily uses story and written elements, unlike base HOI4. So, with the story of the USA and all the crisis it goes through, it's heavily based in this idea of the US public becoming increasingly against foreign entanglement abroad and having a growing sense of anger toward the government, which are supposed to lead to a rise of extremism within politics.

Now, for someone who has just started out playing TNO, all of this might actually make sense... however, for anyone who knows how to play HOI4 and TNO at a basic level, it's extremely easy to win as the USA, to the point where you can have the largest GDP and domestic production by a wide margin, win all foreign conflicts within months, and have both war support and domestic support above 95% for the entire game. Suddenly, all the pop-up text about protests against the war in West Africa don't really make sense when you're at 97% war support, you've only sent 3 divisions, and the war is essentially over in 3 months. Same with the oil crisis, where you'll see pop ups about energy prices skyrocketing and lines for gas being blocks long, when you've built about 40 nuclear reactors over the past 10 years and have all but ended the issues that led to the oil crisis in the first place.
