Bit Tech noticed that Valve may reconsider episodic games, if the market wishes, after Half-Life: Episode 3:
Do the advantages of staying closer to evolving tech and to the consumer’s desires win out over the disadvantages of a constant pressure on developers and more strict release schedules?
In a recent comment to CVG, Gabe Newell has cleared that up just a little and has said that, if the market wishes, Valve may reconsider continuing with episodic games after Half-Life: Episode 3.
"I think what we really want to do is have a couple of examples out there - Episode One, and how long it was to play and how long it took to develop, Episode Two, Portal and TF2 and then the third part of the trilogy; and then sit down with the community and say, 'OK, so what do you want?"
With any luck then, those who hate episodes won't have long to wait until the idea gets canned.
