RPG-inspired tour of Chicago
Otherworld Excursions offers architectural tours led by an RPG designer, who then leads the group through a role-playing session set in the buildings they’ve just seen.
The Chicago “Occult Architecture Day Trip” is led by Kenneth Hite (GURPS Horror and GURPS Cabal) and has sessions coming up on the middle Saturdays in October.

I’ve met Ken a few times. I gave him a tour of my neighborhoods; it was a pretty good time.
