Virtual reality is becoming gaming’s new reality.

The developer kit version of the Oculus Rift, the virtual-reality headset originally funded on Kickstarter, has sold 100,000 devices, according to Gamasutra. That’s 60,000 sold for the original DK1 version and 40,000 preorders for the DK2 kits.

These dev kit versions of Oculus Rift aren’t even intended for commercial use. They’re supposedly for developers looking to use the device to create virtual-reality games and other software. However, anyone can buy a DK2 kit for $350 on the Oculus website. The 100,000-sold mark suggests that plenty of curious gaming enthusiasts are also buying the tech.

When Facebook bought the virtual reality company for a staggering $2 billion dollars last March, the social network founder gushed about its future. “Mobile is the platform of today, and now we’re also getting ready for the platforms of tomorrow,” Mark Zuckerberg said. “Oculus has the chance to create the most social platform ever and change the way we work, play, and communicate.”

Other companies are also making big bids in the virtual reality space. Notably, Sony is creating Project Morpheus, a virtual reality headset for its PlayStation 4 console, while the Oculus is currently a PC, Mac, and Linux device.
