It isn't in game stuff... obviously, but I like it and I like the ideas in it.
Not crazy about the name, as has been said by many in another GOF BioShock: Infinite thread. But that's okay.
Flawed in some ways as it was, I loved that Bioshock's story dealth with themes of Ayn Rand's Objectivism run amok and carried out to its tragic extreme. Personally, I view Rand's philosophy as "I got mine, screw you" and find both it and her personally to be morally and ethically bankrupt. So, the game appealled to me.
I'm excited that the developer this time is taking a new perspective and building on themes of nationalism or jingoism run amok. This time there are themes of racial purity, the power of the state, and allegiance to a collective vision... all things that I also find to be abhorrent and that would be anathema to an Objectivist as well.
Maybe some 4 or 5 years from now there will be a BioShock game set in some Marxist dystopia gone awry. Maybe a city built inside a volcano. I like that these games deal with political topics... and not just in the "those guys bad, we good" way that military shooters do.
If there is a political message in Bioshock as a series, it is likely that extremism in any political philosophy or ideology will lead to failure... something I think most all moderate people can agree on.
I hope there is deeper gameplay and a more nuanced moral choice system and in BioShock. In any event, being a cloud city, you can bet there will be flying :-) and that may be awesome.
