Note to Patreon backers: You received this episode on January 12, 2022, but due to an oversight, it was never posted here. Normally you hear episodes a week in advance, but this one you received seven months in advance! Thank you to everyone for your patience. This is conclusion of the interview. Anything you can call "writing" (science fiction, fantasy, screenwriting, comics, games) Max Gladstone does. He's also a fencer and martial artist. This episode explores connections between these two types of things. This interview ran long, so this is part one of two. Numerous topics covered include: the similarities shared by the crafts of writing and fencing; struggles when writing descriptions of physical spaces; why we don’t see cluttered spaceships in science fiction movies; when to include potatoes in your medieval fantasy setting; designing the layout of museum exhibits, video game spaces, and Walt Disney World; and more!
