Does any of this feel a little...easy, for anyone else? In fact, it's a textbook case of interpassivity: we see an anecdote on social media about capitalism's inherent contradictions unfolding in Dwarf Fortress or communism's victory over capitalism taking place within Victoria 3, declare our own sympathy toward this, contenting ourselves on the inevitable victory of communism over capitalism, and then return to our lives in which we probably aren't doing much of anything to bring about capitalism's downfall, much less that inevitable victory of communism's. The crux of the matter is regardless of whatever happens within these games (which, we should keep in mind, are never neutral descriptions of reality), we're dealing with a world in which communism has yet to effect itself on a large scale at best, and suffered a resounding defeat over the course of the 20th century at worst. Confronting everything this would imply is gonna demand significantly more than social media posts could ever hope to contain.
To come at this from another angle: in the case of Victoria 3, the only reason we're able to impose communism on whichever nation we're leading - or at the very least, to passively let it develop on its own - is because we're not really bound by the systems and societies we interact with. We don't have to be bound by the ideologies these 19th century institutions impose on us if we don't want to be. (One has to imagine this as a fundamental limitation in what Paradox Interactive could design. They can't exactly send us back to the 19th century, after all.) Contrast this against Micaiah's arc in Fire Emblem: Radiant Dawn. She, too, wants to gain the power to reform corrupt systems that oppress the weak, but because she has to do so from within the world she hopes to change, she has to make various compromises over the course of the story that ultimately mold her into the kind of person who will unconsciously uphold the very systems she seeks to change. After all, she can't affect the change she wants without the power those systems offer her. This ends badly.
