If Hostile is based on the movie Alien, Zozer Game’s Godstar has a lot in common with Frank Herbert’s novel Dune or Free League’s Coriolis game. Of course, it’s neither. There are no sandworms, spice or Icons granting magical powers. The planet Aurelia attracts pilgrims as it has a sentient star that can be consulted (for a large fee). It gives out practical and scientific knowledge, not the meaning of existence. Aurelia is also the centre of administration for the area of space around it. The game is about playing the various people and factions that live on Aurelia. You can include as much as you like about the influence of the Godstar, I thought it was not essential to involve it. Godstar’s a supplement, you need to have a copy of the Cepheus Engine rules (or one of the versions of Traveller) to make best use of the material. The nice thing about this is that even if you don’t want to play in this setting, it’s really good for things to use in other games.
