Gabe Newell

Famous for: Valve, Half-Life, Steam

Game Newell is one of the most accessible people in the industry. His e-mail (gaben@valvesoftware.com) is well-known by the public, and while he's not exactly forthcoming with information he doesn't feel like sharing (do we have to say it?), he has been known to drop occasional tidbits. As a co-founder of Valve, the company behind Half-Life, Left 4 Dead, Portal, Team Fortress 2, Steam, and more, he's in a position to be as discerning with his tips as he wants.
