If you can buy into these three tenants as defining rules for an episodic game series, it begs the question: why bother making episodic games at all? The answer is not an obvious one when you consider that this content model presents a lot of challenges for an industry that, historically, has not been good at producing quality content in the studio-like TV show model that episodic game development would demand.
I am left with a bad taste in my mouth personally regarding episodic content, but that’s primarily because Ritual pulled out early and don’t intend to deliver the 2nd installment to their nine part game. I think if companies plan to do episodic content, they should be certain that they are able to pull it off. While Valve doesn’t have to worry much for support, other companies like Ritual do.
