a repudiation of Ayn Rand and objectivism? Because I've read many reviews about the creator's intentions to show that her world (like in Atlas Shrugged) is a fantasy at best and any little niche could bring it to its knees.
Also.....how does this game end? What is its conclusion?
I think it is. Though I think Andrew Ryan (similarity of his name with Ayn Rand) isn't the most fair representation of her ideas. Whereas Ryan was completely immoral, Rand was something of an overly moralistic bore. According to Wiki, the plot was based on a critical review on one of her books that so infuriated her. Ironically, the gangster 'Fontaine' guy seems more like Rand then Ryan, and he was a worse human being.
There are three endings to the game, good, bad and worse. They are all based on how many little girls you saved. Youtube at least the good ending, I think it is most likely to be the most canonical one.
It couldn't be a repudiation of Objectivism so much as a comment on it's feasibility. Where Objectivism was shown to be working, it was working well, and it wasn't shown to be breaking down due to its own flaws, but where it was departed from due to being exploited, co-opted, or to as a reaction to exploitation/co-opting.
If it was intended to repudiate Objectivism, it really didn't do such a good job; as DrM said the characters weren't fair representations, and there wasn't critique on clearly Objectivist principles so much as on their distortions.
I'm neither pro nor anti-Objectivist; it makes some good points, but some of its premises and conclusions aren't so sound, and this game either missed its opportunity to explore those, or only pretended that was its goal.
