Episodic Content (Score 1)

One of the things the writer overlooks is the ability to release content in episodes. Instead of charging $30 for one game, a single adventure can be broken up and released in episodes or chapters for $10 each.

Penny Arcade and Strongbad have both successfully used this model and it also gives customers an opportunity to try a game without committing to an entire series.

This may even be good for independent developers because they would get feedback and money before completing development on the entire series.
