GameTap is taking a most unusual approach with its first weekly episodic game series. Each episode of American McGee's Grimm – individual "fractured fairytales" from the designer of American McGee's Alice – will debut as a free download and remain free for a 24-hour period. After that, episodes will go into GameTap's archives and be available to download individually for a yet-to-be-determined price.

The model is likened to that of the iTunes or Xbox Live video download services. Catching a Grimm episode during the initial download-for-free window will be like watching a new episode of a show on network TV. Once it's "aired," you can download it if you missed it – for a price.

The episodes will be supported by minimal up-front advertising and the first one, "A Boy Learns What Fear Is," will debut on July 31. We had the opportunity to play the first three Grimm episodes yesterday and will post our impressions later today.
