I've played some RT, and yes, it's crunchy as all get out, but there's a fair bit of diversity in the classes and between members of classes. I ran a Seneschal, built as a Master of Secrets, I had more spies than the Arch Militant had bolter rounds, both within the ship and within other organizations. I could have just as easily built a highly efficient merchant.
Fun system, I'd be inclined to run it at some point in the future, though not right now.
