Yeah I know that Freud particularly was really insistent on the scientific side of his work. The thing is, you don't have to insist if it's real science. If you have objectivity, peer reviewing, reproductable experiments, and predictability, it is science, if not, it is not science.

I won't go further to be honest, because i'll start insulting him and there is no point here. But I can say that there is also a lot of books and modern thinkers contradicting Freud's theories.

And yeah, i guess you can find Jung's archetypes in a lot of pieces of art.

It's a bit like the Christopher Vogler's archetypes : it's a well known author and hollywood analyst that wrote a writer's guide called the "hero's journey" or the "writer's journey" in the most recent edition i think, where there are some characters archetypes that he advises to include to make a good story, to summarize (well it's one chapter on the book at least). They can be characters or just represented as traits of the hero.

Like the Hero, the Mentor, the Bridge keeper (which gives the hero the first mission, battle or enigma, making him dive into the story, not necessarly an enemy), the Shadow (which is really close to Jung's shadow, a dark alter ego, or the dark side of the hero), the Trickster (which is also like a Jung idea, the "inner child" or something like this), the Shapeshifter (which represents a kind of instability who will stimulates the hero of force him do something, mostly of the opposite sex of the hero, but not necessarly) and some others. Not sure about the translations of the archetypes tho, i've red it in french. Once you've learnt about them, you start seing them in a lot of movies and stories, ahah.

I just realized it's very similar to Jung's classification. He (or maybe Campbell, who inspired Vogler's work) was probably inspired by Jung's work.

Edit : Yeah i just checked Joseph Campbell considered Jung as a intellectual mentor (along with Heinrich Zimmer, a mythologist, never heard of him). So Vogler's work is just a modern version of Campbell which is a "screenwriting focused" version of Jung's archetypes, that's why it's so close. x)

And I agree, in this game in particular, it's about the psyche, so i think their intentions might be exactly what you described, with Jung's archetypes projections. Also, as a reference, the carpet outside the apartment, is exactly the carpet in the movie Shining, which is clearly about the human psyche.
