Fantasy game with an integral non-conventional fantasy setting consisting a a bizarre and fantasticated version of early Victorian Europe.
Live-action roleplaying (LARP) rules were included in the Comme il Faut supplement.
Castle Falkenstein was also adapted to GURPS, for a pair of sourcebooks and a Pyramid Magazine article: GURPS Castle Falkenstein, GURPS Castle Falkenstein: The Ottoman Empire, and The Realm of the Inca. They were written for the Third Edition rules, but characters can be updated to the Fourth Edition rules with the help of the GURPS Update conversion guide. The Fourth Edition equivalent of the magic system is the Energy Gathering variant of Path/Book Magic in GURPS Thaumatology, but if you don't have that book, you can just use the original rules with little trouble. The Faerie powers can be confusing to convert, however. Players can get help on the Steve Jackson Games GURPS Forum if needed.
