And not entirely appropriate for this game. As the title of the posts says, right name, wrong game. There is a flaw in this system which could be a typo or perhaps something intentional.
I have mentioned several times that this game seems to have some aspects of Traveller, a very simplified version of Traveller. In some respects that is true. The plots, the technology types, even the Antelope starship itself. But that is where the similarities end.
In studying this game, I have come to the conclusion that it might have been a stand alone game used by the author for a science fiction setting. Some sort of super campaign.
One of the hints at this possibility is the combat system. It is really designed well for ship to ship combat where smuggling and piracy are critical.The game system has tech levels, from 1 to 6. For spaceship combat, you are able to roll one die for each tech level of the ship's guns. For tech level 6, you can roll a maximum of six dice.
