What a great free book. I got this from a link from a guy on my local gaming guilds' meetup post. This was awesome. Great character creation tools, great planet, races and scenario creation system. I love sci-fi and with a few throws of the die in preparation you could be off exploring your newly created sandboxed universe with your friends in no time at all. I love this book. There's also an african tribal add-on that just came out recently that I downloaded as well. I'm no GM but I can't wait to find a group to GM this, hell I would play EVERY week if they had this.
