One of the things that made me interested in brink was it's setting and back story. The game looks pretty unique and colourful for an fps and I've never seen anything like the Ark before. The idea of Instant/Deep Context, letting the environment tell the story is very interesting to me and it's not often that the question of "Who are the good guys and who are the bad guys?" is left so open. (In the games I play anyway.)
I'm wondering what you guys think of the setting and story. Do you think it really that original? Do you care about this kind of stuff or do you just want to play the game?
Here the developer diary about Instant/Deep Context, the story and setting, though you probably know this stuff already.
