The ruleset is interesting (I love the task resolution) but it reduces crunch a little too much and really runs counter to some of the things the show was really about.
The show featured a ragtag group of scoundrels struggling to get by. In this game, they have nothing to worry about since there is no money really and they can just make items appear from thin air with "plot points." This really rubs me the wrong way. Don't get me wrong, I like rules lite systems. I also like that this game gets rid of HP bloat and Monty Hall itemization. However, for a game about a group of folk out in the verse just scraping by, there needs to be more emphasis on basic equipment loadouts, trading, job payouts vs fuel/food costs, etc.
With some basic mods (particularly to how assets/signature assets are handled) and some additions (hack in a some stuff from Stars Without Number), the rules can be good. I would also consider tossing in Savage Worlds-like card dealt intitiative since it leaves turn order up to nothing but DM fiat.
If you play as is, the game is fine as something to occaisionally jump into but it won't do as good as other systems when it comes to more open space campaigns.
