Admittedly, it's our first Itch game https://kadormazing.itch.io/movement
But it deals with the themes you talk about there. Also has those references to Rome, fascists etc. When it's being serious at least... At times, there's some DUMB humour.
The one thing it doesn't touch on too much is the current problem we face probably: manipulated - perhaps ignorant - people not caring about truth if they think truth doesn't benefit them. There's some in-game email I think where a cynical guy makes an axis chart and says the problems are in these four quadrents (stupid + bad people. smart + bad people. stupid + good people). Eh but it doesn't take itself too seriously. It's free. But it's long.
