But which episodic content have we been fleeced by?.... Apart from UT2K3, of course;P
In my opinion, any successful franchise becomes episodic. Valve is speeding up the process, which I kinda like... The whole cost per hours doesn't ring a big bell for me.... I don't know how long a game takes me to finish. I never ever time it. At the end of a game, I either enjoyed it and can't wait for more or I put it down to not being my thing.
Also, I liked some of those big open, empty, areas in HL2.... gave me a real sense of desolation..... like the world had been fleeced, prior to us personally via episodic content;P
