Well think about it. If you're gonna be living there for months or years, you're gonna want the ship to look at least a little pleasant ya know. Just because it's a spaceship doesn't mean it has to look like a prison facility. I think USS Enterprise had carpeting and other decorations, so it wasn't always cold, hard metal. @Void - I pretty much agree with everything else you said. Here's one to include: A board/council that does nothing but try to hinder and obstruct the protagonist. I get it, corrupt executives are corrupt and all, but I would think they'd know the protagonist has the interests of whatever organization they're in at heart, so why would they make doing that difficult for the protagonist?
