HL2 Not Required For Episode 1
Eurogamer reports that Half-Life 2 will not be required to run Episode 1, the first content pack for Valve's hit game. From the article: "Half-Life 2: Episode 1 won't actually require Half-Life 2 to play, Valve's explained, and although the game will be 'four to six hours' long, marketing director Doug Lombardi reckons it's 'markedly richer' in terms of content quality ... The change from Aftermath to Episode 1 was 'simply a name change' he says, when asked about the shift to episodic content - which wasn't a shift at all, he adds, since 'the format of episodic releases was decided before Half-Life 2 was made available'."
The way I see it, ValVe has two options :
1) Release each episode at $9.95 a pop, making it reasonable for people to purchase them now, as well as future episodes.
2) Stifle the Star Wars-esque episode crap, and just dedicate resources to a full expansion & engine update.
$20 seems a bit excessive for a glorified map pack, and I certainly wouldn't purchase multiple episodes at that price. If I wanted the proverbial carrot on the stick, I would've stuck with WoW.
