This one slipped by me last month. At the end of last year, GURPS Disaster: Hurricane came out for incorporating hurricanes into your roleplaying games, and GURPS in particular. Roger Bell West was one of the playtesters and asked me if I’d contribute a set of design notes to his e-zine, The Path of Cunning.
Anyway, it was published in November and includes some basic notes about why I wrote the supplement, the decisions made during development, and why. While you’re there, check out the rest of the website. There’s a lot of good stuff there.
