I'm under the impression that although gearbox has an incredible amount of leverage on building original content, alot of people just want them to stick with what has been seen already in the films. I'm all for it, but i'm also interested in seeing what they intend to make authentic and still have something incredibly original and freighten us. I can't say much for the alien side of things but I think they nailed down anything to do with construction and architecture (ala syd mead designs) which is great but you know there is collumn A and then there is collumn B. collumn B is slacking.
Thats just my opinion. I could be wrong. so wrong.
