The thing about these sci-fi languages that I've always thought is silly is that on Earth we have, what, about 6,000 languages? But sci-fi worlds tend to have only one language for the whole planet. Or does that mean that we silly monkey-men have not yet evolved and progressed to the point where we are all one cohesive yellowish, black- brownish,reddish whitish bald race with purple goo on our heads and speak a singular guttural language?
Although I have to say, if this is a trend for Australia, watching "Crocodile Dundee" with Klingon voiceovers would be awesome!
