A new
Steam Update (thanks Frans) on Half-Life 2: Episode One discusses the add-on's plot and describes Valve's frustration at Half-Life 2's six-year development
cycle as one reason for the move to episodic content. The update includes a
thumbnail with a broken link to
this screenshot and a broken link to the recent
Robin Walker Q&A on Computer and Video Games.
True. The numerous steam updates concerning these valve titles and the corresponding news item they trigger make the development times seem even longer.
