So, my contention is that all the locations, countries and historical events have been invented, but some political terms (and musical genres but it is less important) are the same as in our world. However these words have a massive historical significance so they can't simply be used in a fictional context without a lengthy explanation of their significance in the fiction. For example, words like "communist" and "socialist" are used, including in the main protagonist dialogue options, without any previous explanation.

After having played a couple hours more, both the protagonist and myself got more information on the historical events and it felt easier to pick political answers that were closer to actual political sensibilities the protagonist could have at the stage of his remembrance. But every time I've been put on the spot before that, I have been choosing the evasive option because even I as a player wasn't sure what the more politically committed answers meant in the context of the game world.

This actually triggered a special internal monologue where the protagonist branded himself a centrist for a lack of political leaning, and I felt it was a little unfair given that the protagonist has a complete amnesia at the start of the game, so even if he had any clear political leaning before the amnesia, he wouldn't be able to have any shortly after the amnesia occurred for a lack of memories about historical events and the actual political currents.

I actually appreciate that they came up with a couple original political terms like "moralism" and "ultraliberal" because both the player and the protagonists can discover them at the same time without any real-world baggage that only the player can have.
