yes, wolfgang, theirs been a player update, since i posted that, i've earned enough GC from space trade to buy over 40 docks, thats over 8000 GC, if you include my professional soldiers stocked, registration for a couple of CEOs, and several hundred pop, i'd say, i've made well over 10K GC
but it wasn't anything the GM did, space has been about the same for 5 years, the change has come in how players approach space.
you have to sell goods at 1/3 the GC converstion, to make it worth it for buyers to pay. that is, for one GC, you'll need to offer about 100B value, or better. plus, most of the demand is in military weapons, on the Crucis, Cervus, and Carina stations.
if the game was more popular, i can for see non-military goods with demand. i've already sold maybe a couple hundred GC worth of FMUs, and AMUs. and made maybe a couple dozen sales of gasoline, and aircraft fuel, at 0.07 for 10M tons og gasline, you can't really boast, but it does prove that these products would go, if more people where playing
you have to ask, why would a person spend GC to buy a shuttle, GC to rent a dock, to buy something at a price equal to what they'd get if they just converted the GC to cash, and bought it themselves? so to make it worth it, you have to way undercut the price.
