Both the companies are very well appreciated, and when it’s like that some things are accepted by your supporters. Mostly because they already achieved big hits (and so big money).

About Valve, it’s also true the pressure thing, but Gabe Newell was already … Gabe Newell. Charisma is everything ;-)
