Typically a term used for consoles, a "Killer App" is the game released on that respective console that is just so good that gamers just have to cave in and buy that console in order to play that game. Nintendo has always had Zelda and Mario games as their killer apps, Microsoft has had Halo and Gears of War, and Sony has had Ratchet & Clank, Uncharted, and The Last of Us. Over the last few years, people have been wondering if VR would get a killer app. There have been a lot of standout VR games over the last couple of years like Rec Room, Lone Echo, Arizona Sunshine, and GORN among others like the recently released Skyrim VR, none have quite assumed the mantle of VR's killer app. Maybe we have that game now with the release of Beat Saber.
