Episodically: Greatly depends on how long and self-contained the episodes are.
I mean, you can have a series of adventures that take place in the same universe (Monkey Island, Larry, Spacequest, King's Quest, etc.) which you could technically consider episodes, but they are all self-contained.
Chopping up a single adventure storyline into multiple seperate release chunks (is this what you are asking?) sounds like a bad idea, since you would impose your schedule on the player rather than having him/her play the entire thing at their own pace.
*especially* since you are talking about trying to make things interesting and challenging for your players, you should consider how much more disjointed and less immersive it would make it for a player if they have to wait -x- time for the next chapter to be released, rather than playing it through start to end in a weeks time on their own schedule.
