Like other platforms, the Oculus Rift and HTC Vive have shared titles and some exclusive games to boot. Unfortunately, that means you'll miss out on certain listings depending on which you opt for. Luckily, it's now possible to play a select few Oculus Rift exclusives on the Vive.
As covered by The Verge, a proof of concept program on GitHub called LibreVR allows both Lucky's Tale and Oculus Dreamdeck to be unofficially loaded on the Vive. Obviously, you'll need to own the titles you wish to port to the Vive platform, and while it hasn't been tested on titles other than the two aforementioned, it is noted that this program should work for future ports.
It's good news for those with the Vive who wish to enjoy the same exclusive content available to friends wielding the Oculus.
