Virtual reality is coming whether you're interested or not. Soon, gamers will have the opportunity to equip fancy headsets and--for the first time--simulate exploring a virtual world from within rather than through a TV screen. That's exciting! But what, exactly, should we expect in terms of gameplay experiences? And what are the challenges involved in creating those experiences?

When we talk about virtual reality, surely we're not just talking about turning our heads into a camera so we can play Call of Duty, right? I'm not a game developer; I can't really say--so I reached out to some folks that work in VR and games to find out. Anton Mikhailov, an R&D engineer at Sony Computer Entertainment working on Sony's Project Morpheus, and Sigurur Gunnarsson, a senior programmer at CCP Games (developer of EVE Valkyrie), were kind enough to shed some light on what separates VR gaming experiences from the traditional ones we're so very familiar with.
