Query: Excellent RPG

This game is very well written with the entire text in the general spoken word style of "Firefly" and "Serenity". The system is different, but still pretty intuitive once you look at it. There are 2 sample crews (of course, one is that of Serenity herself) and a number of ships Alliance and privately-owned. If you're a fan of the series and even somewhat interested in RPGs, you're very likely to enjoy Serenity RPG.
