Armitage Files is getting a lot of actual play, with groups running it for more than twenty sessions, as this thread on Yog-Sothoth, chocabloc with useful hints, demonstrates. Armitage Files encourages Keepers to incorporate player-made clues into the mystery – it’s not quite a do-it-yourself game such as InSpectres, but along the spectrum towards it from a Keeper-led mystery.

One Keeper, who has not played Trail before, is running Armitage Files as his first game. He and his players have created an intriguing blog – Keeping Cthulhu – which I’ll be following with interest.
