If the VR game you picked is developed by Ubisoft, you won’t need to worry: the company’s VR titles will support cross-play between all three platforms.
The recently released competitive game Eagle Flight, as well as the upcoming games Star Trek: Bridge Crew and Werewolves Within will all feature support for multiplayer between PlayStation VR, Vive, and Rift. Red Storm senior creative director David Votypka said that this was necessary due to the emphasis Ubisoft has put on social VR.
“Our games feature strong multiplayer experiences, so letting friends play together regardless of which headset they own will enhance the social nature of our games and let them be played the way we envisioned,” Votypka said in a post on the UbiBlog.
Cross-platform play between PlayStation VR and other headsets isn’t especially common, but it’s not unheard of.
