You know you say Disco Elysium and what I've liked about its portrayal is how fair it is, which is extremely rare and shows the creators know what they're talking about. You meet multiple groups of communists and all of them are coming at it from different angles, because it's set in the aftermath of a failed revolution. The protagonist himself comes off as hilariously naive, because he's some amnesiac cop wearing disco pants who lost his mind and genuinely out of nowhere decided he was a revolutionary. The decision gives him an inflated sense of self-worth and earns him the respect of basically nobody. The other few I can think of are the union leader, who is doing things like real estate scams and covering up murders. There are the students who run a leftist club, but they're largely inert scholars who meet in a dilapidated apartment talking high minded theory and not organizing. There's the final antagonist, who has absolutely lost his mind and is trying to rekindle a movement that died decades ago. All of the characters are trying to deal with the world that's been given to them and come up with their ideological positions from those circumstances. It's neat.

Also a really good game is To Build a Better Mousetrap It's just a short flash game but it gets the point across pretty quickly. It's about managing a factory that builds a thingie. Thingies are sold to generate pellets to feed your workers. You can also research automation to replace workers with robots, but you also have to manage an increasingly belligerent mass of unemployed mouse people. Workers also get mad if they're not paid on time. So you've got to manage a contradiction of increased automation not helping anyone except you, the person in charge.
