GameTap's Thursday update brings a new episode of American McGee's Grimm, which is free to play for today, while their new free game for this week is Rogue Trooper. Included in the new premium offerings on this online game service is Fable: The Lost Chapters. The new Grimm episode is the story of Pinocchio, and surely your nose will grow if you claim you need a description of that one. A glitch prevented today's additions to the catalog from going live until just now, but it is not clear if free access to the Grimm episode will be extended to a full 24 hours from now.
