Ran Ray Otus’s Sinister Solstice (with a number of variations) for a second time as a oneshot with a group of experienced roleplayers who hadn’t played DW before.
People had fun and the system seemed to go down well. This group took an entirely different route/approach than the previous one, which really kept me on my feet! Took about 6-7 hours to run through.
Sound about right! We played it out over three 2-2.5 sessions.
