Steve Jackson Games' e23 managed to surprise me very slightly by putting another of my old books out in PDF form.
GURPS Castle Falkenstein was a little unexpected in this context because it's about a licensed third-party setting, and the company needs to renegotiate things with the IP owner to get those books re-released as PDFs. However, it may be less surprising that the company managed to negotiate an expansion to this license than would be the case with many; unlike, say, Conan (not one of mine, but one which recently made a similar, more surprising GURPS/e23 reappearance), Falkenstein was licensed from another games publisher, who'll have a realistic view of the possibilities, and who won't have many other uses in mind for the IP.
Anyway, it's a book in which I take a little pride, and it's a chunky volume with some nice art. (I should also point out that it was a collaborative effort - the one book I've done with the admirable Jim Cambias.) So I'm happy to see it out there once again.
