Time and Space
More DellCon, another space-themed game. (I did play several others, honestly).
This one is a bit of a blast from the past, albeit a reprinted blast. Merchant of Venus has been around for decades and is essentially the same model as the BBC micro game Elite. It's a challenge in, initially discovering, then trading with star systems, where finding efficient trading routes is critical.
Entertained to find one of the alien races being the Dell.
