I saw the first BI trailer, and at a point I was like, 'wait... is this a metaphor?' I still don't know if the things that happen on the first trailer, in game, are an allusion to something I haven't figured out yet. The way it's set up, the framing and so, looks like it, but from what I can tell it might as well be aping a cinematic trope without fully grasping its meaning.
The other day I was thinking about how Bioshock is good because it criticizes a liberal viewpoint. Games, and most art forms I guess, as well as those who enjoy them, are usually liberal, as far as they're willing to articulate their political beliefs anyway. If Bioshock had based its gameplay on a conservative scenario it would be essentially preaching to the core. Of course Rand's Objectivism of 'if I'm paying for these roads I don't want those poor freeloading bastards to use it' is essentially the strawman of the left wing, but it's still more appealing than if it had just echoed the 'following tradition and limiting freedoms is bad bad bad!' the genre as a whole already has.
I still think it's hilarious the way Americans profess their love for their country, it looks hilarious for those of us outside. As far as the concept of BI goes I love it already.
