I recently played A Will to Murder, and I wrote about it on the Freeform Games blog.
Mo described this on Facebook as me eating our own dogfood.
I do feel that playing A Will to Murder is a lot more enjoyable than I imagine eating dogfood is.
Unless you're a dog, of course.
(Monty, our 7 month old golden doodle would probably disagree with me. He likes dogfood. On the other hand he's never played a murder mystery larp, so I could be wrong.)
