What are the challenges working with an established setting like Call of Cthulhu?
Similar to designing 3rd Edition D&D, you’re messing around with something that is beloved by many people. D20 CoC was kind of a risk in that way. But the task was to show that d20 could handle something very “un-D&D-like” and I think we pulled it off. As far as something like Shandler goes, working within the confines of the Cthulhu Mythos is like hanging around with old friends. I’ve long been a Mythos fan, and I’ve run a lot of Call of Cthulhu over the years, so coming up with the plots comes very naturally. As I mentioned before, though, I don’t like stale ideas, so I try to give my own spin to things that are very familiar.
