Narrative-driven games give players the illusion of choice. To me this seems like it would lend itself to being even more effective than traditional propaganda because it’s capable of tricking the player into thinking they came to a conclusion on their own.
Don’t get me wrong, I love Disco Elysium, but it is very effective communist propaganda. Propaganda has a negative connotation but is not inherently bad or dishonest, though it certainly can be.
