Whether you think steampunk is the coolest thing ever, or it's just what happens when goths discover brown, this is some interesting news for RPG as a medium. Abney Park is working with Cubicle 7 on an Abney Park RPG. The announcement has a mockup of a book cover for you to enjoy.
My first thought (and comment on the site) was that it would make for a great supplement to Swashbucklers of the 7 Skies, but that might not be true. I haven't finished reading S7S yet but the swashbuckling might not quite be the right fit for Abney Park. As long as the rules for the new system make stories which are different to S7S, it's a good choice.
More interesting than this, though, is the crossover between a band that occupies an alternate reality and an RPG. There have been musicians like this before. Gorillaz do it nicely. Queen did it with their Queen II album. David Bowie did it again and again. You could argue that Flight of the Conchords do it. I think this is an interesting foray by RPGs into another kind of intellectual property. Books, film and TV have been done, successfully and dismally. The choice of the fictional world of a band is not such a stretch.
And that's the new challenge for you budding designers. Make the RPG for Gorillaz, Queen, David Bowie or Flight of the Conchords.
