At Santa Clara, CA-based Green Throttle Games, he's working to give smartphone owners a way to display games on their high-definition TVs and compete with their friends via Bluetooth game controllers. Since coming out of stealth mode in November, the company has raised $6 million in venture backing and has begun to share previews of the first Green-Throttle-enabled games. In an in-depth interview, Huang and co-founder Matt Crowley argued that the era of $60 game discs is almost over, and that today's smartphones have more than enough power to run high-fidelity games on big screens. He says the company's key technical challenge has been building a software platform (called Arena) that allows a smartphone to handle inputs from multiple controllers. 'We’re talking about allowing four controllers to connect to the same device, and having the device know who Player One, Player Two, Player Three, and Player Four are,' says Huang. 'That use case doesn’t even exist in mobile.' Huang expects Green Throttle's first games to hit the market in early 2013."
