Portal Writer Erik Wolpaw Leaves Valve
Erik Wolpaw joined Valve in 2004 and has since worked on games like Half-Life 2: Episode One, Portal 1 & 2, and Left 4 Dead, but the writer has recently left the company.
Wolpaw hasn't commented on where he's headed next, but he was already working with Double Fine on the release of Psychonauts 2, so it's possible that he'll focus more heavily on that project.
I wish Wolpaw the best. Anyone who has played a Valve game over the last decade knows that Wolpaw is a funny guy, and I'm sure his voice will be sorely missed from the company.
