Steam Success Holding Up Half-Life Development?

donniebaseball23 writes "Steam is a huge success, and it's arguably the leading digital distribution platform for gamers on the PC. But has the growth of Steam's business led to a slowdown in Valve's own games development? Is the so-called 'Valve Time' actually a symptom of Steam's hogging Valve's resources? That's the argument that Stardock's Brad Wardell made this week. 'If you were to look at a timeline of games developed in-house by Valve – not developed externally and then acquired – and you look at before Steam and after Steam, it's definitely had an effect,' he said." It's probably also slowed by the imminent launch of Portal 2, which is due out next Tuesday in North America.
