I'd like to see more trader stuff. I mean it's called "Intergalactic Space TRADER" and a big part of that is business calculation. Otherwise it would be called "Intergalactig Space DELIVERY GUY", right? :)

i.e I can imagine some volume discount system, maybe an expiration date on certain goods, more overall market involvement (supply & demand).

I know that creating an economic backround system is very hard, but even a simple system would add more live to the otherwise lonely me-unviverse :D And more events. And more blips. And... ugh.... ;)
