Fahrenheit was indeed originally designed by David Cage as an episodic experience on PC. But back in 2002, this was considered to big a risk to take for a publisher. Vivendi Universal Game however like very much the story and the overall concept and asked David to redesign the game as an "interactive movie" rather than an "interactive series". We see a great future for episodic content, however only for those titles which will really take the most out of the format. You don't design an episodic game like you'd design a full game. A TV series has a very distinctive structure than a feature, with its rhythm, twists, characterization...and very own business model. The same will apply to episodic gaming and Quantic Dream is discussing potential projects today with major industry players. SIN Episodes will be distributed on-line and in slices, I do not think however SIN really qualifies for the denomination "episodic", at least not how we understand it.
