This seems like a good opportunity for a bit of self-publicity. You might be interested in Castor and Pollux, a choose-your-own adventure I GMed last year. Obviously it's too late to affect the outcome now, but playing through it should give you an idea about how the game might feel. Factions feature strongly especially in the later part of the story, although a lot about them has been embellished based on the information Frontier had given us at the time.
