For the aesthetics, of course! I'd argue that stations and outposts ARE pretty lifeless - yes, there's other ships using other landing pads and some yellow lorries trundling round the rimroad, but it's not like there are gangs of dockers waiting to attach refuelling hoses, or cargo loader robots, or a couple of likely-looking mechanics with hammers ready to unbolt your beam lasers or... well, you get where I'm coming from.
It's an
illusion of a working station. The different voice actors that issue docking instructions adds to this illusion (and very well, if I may add). And, to be fair, if we could get something like that for planetside city docks, I'd be pretty pleased with that alone. Anything else is just icing on the cake.
My imagination (and/or my g/f) will fill in the bits where I slope off to the Pleasure District for some Holo-Me "multicrew" action...
Oh, and will one of the mods please give this excellent thread a better title already!
