From the introduction:
Welcome to the first installment of Adamant Entertainment’s Star System. Our goal with Star System is to provide you with support for your space-opera campaigns, whether you play Saga Edition, d20 Future, Traveller, Serenity, or any other SF game. To that end, the elements we include will be system-generic so that you can drop them into any campaign, no matter what system you use!
In order to make Star System more utilitarian, we’ll be using generic terms when we describe characters, starships and creatures, which can be easily translated into your campaign’s particular game system. Adamant Entertainment is providing this free introductory guide as a key to those terms, and as a special bonus, the previously released Space Opera Adventure Generator is incorporated into this guide free of charge! You’ll never be stumped for ideas again!
