Interesting that the game references the Encyclopaedia Galactica; that is mentioned in The Hitch-hiker's Guide to the Galaxy, but that was just making fun of it; the Encyclopaedia originally appeared as a serious concept in Isaac Asimov's Foundation saga (the original Hitch-hiker's Guide radio series was made in the same BBC studio in which the first three Foundation books had been serialised a few years earlier, so I think it's pretty likely it was originally conceived as a parody of it). If the creators of this game are fans of Foundation, it strikes me as unlikely that they'd be especially keen on hyper-individualist philosophies like "Objectivism;" at the heart of the Foundation saga is a concept called "psychohistory," which is all about predicting the complex interplay of different social forces and movements on a vast scale. In this model of human behaviour, individuals - even incredibly rich, intelligent or powerful ones - have literally no relevance to history whatsoever, other than at certain special and rare once-a-generation-or-so key moments called Seldon Crises when everything comes to a head and somebody finds themselves in a position to make a key decision that will set history on one particular path; otherwise only very large scale collective action over very long periods can have any influence on humanity's destiny. I can't help but suspect that sincere Objectivists would despise such a notion, and any works associated with it.
If Ross hasn't read those books, I would highly recommend them, they do a lot of that charting-the-trajectory-of-human-civilisation thing he mentions liking so much in Deus Ex and this game. I would suggest not wasting any time on the recent Apple TV series of the same name, however; it barely resembles the books at all, and seems to have been written by someone who a) didn't really get the point, and b) clearly wanted to write something else of their own anyway.
