As you may remember, I intend to drop CT-style trading entirely, as it’s too much like the day job.
For face-to-face play, I eventually came to the conclusion that like space combat, trading wasn’t much fun for most of the group, as they had no direct involvement in it. My final ruling was that trading happened in the background, and the profits it generated exactly balanced the ship’s upkeep – life-changing amounts of money could only be acquired through adventuring.
However, trading serves another function, in that the goods the PCs buy direct them to their next stop. You look for the place where your cargo will get the best resale DMs, and head that way.
In Stars Without Number, the activities of the factions should replace that; but if not, I will need to find some way of turning Stars Without Number world descriptions into Classic Traveller ones, to determine trade classifications.Shouldn’t be too hard; if it turns out to be necessary, I’ll give it some thought and post my findings.
