There's a quantity of gimmicky cheap trump-based games, they sell pretty well. Like, stick a trump in it and get edgy. One is a parodic trump-body-guard simulator, another is a surgeon simulator dlc, it's that kind. Such goat-sim cashgrab don't easily pass the gog curation, though.

Then there's all the Civ games, which basically end the way our planet ends (with pollution-driven temperature increase, which is the fate that trump has decided for all of us because of the system of exchanges that humans use which is based on symbolic currencies which accelerated hoarding is more fun than planetary survival).

Then there's Papers Please, which takes border bureaucracy to an extreme.

Then there's Far Cry 5, which takes place in the USA and pit you against christian fundamentalist rednecks of some sort.

And then there's all of ww2 games that involve countries driven by autocratic, nationalist, militaristic regimes pretty hostile to minorities.

Then there's various election-based videogames, from Democracy 3 to Political Animals.

Then there's all the RPGs touching on racism through the very clumsy and counter-productive allegory of elves/dwarves/human species (which, well, are species, and do show deterministic features in universe, so, well played guys).

Then there's all the games about evolutions that attempt to illustrate natural selection but, because they are games, and you are a player, end up as intelligent design simulators.

And then there's the winkwink jokes of various adventure games, I suppose.

And then... oh, I must be forgetting about one or two hundreds other genres.

Do Civil War-era wargames count ?
