Valve enjoys keeping secrets. And while I’m beginning to suspect that Half-Life 3 will ultimately turn out to be a giant ray gun that erases all memories of the Half-Life franchise from our brains forever, there’s one thing Valve’s been uncharacteristically upfront about: its fascination with the future. Wearable computing, augmented reality, and – perhaps most pertinently, given recent extremely promising developments – virtual reality. During QuakeCon, I got the chance to sit down with Valve’s most vocal proponent of these new technologies, programming legend Michael Abrash. However, while Valve’s obviously putting some serious work into breaking new technological ground, Abrash was quick to point out that it’s still all in service of a singular end goal: entertainment.
