Samurai Gunslinger, he say Browncoat gamers rejoice! since Fox has licensed a company to turn the series into an online RPG. My first reaction is that this is going to be every bit as popular as Empire of the Petal Throne and other such RPG set in worlds run by totalitarian regimes*. The oppressive government of the Alliance doesn't strike me as providing much scope to freebooting freighter captains, and as we see in Serenity, the demimonde that might support such nonconformist rebels is all too easily burned out of existence. Besides, if you want to play tramp freighters in space, there's already EVE. Don't get me wrong, I'm all for more product coming out for the Firefly franchise, since it all supports the possibility that another movie or direct-to-DVD series might eventually be made, but I can't see spending $15/month (or whatever they charge) to play in that universe.

*Greg Costikyan had The Price of Freedom, about rebels in a future America that had fallen to the Soviets. That one didn't sell too well either, IIRC. On the other hand, there is Paranoia, but that's for laughs.
