There are many games for vr that cannot be done without the tech. It isnt all about immersion but facilitating unique experiences.

What held it back from mainstream imo is an inherent space issue (you need room) and a lack of multiplayer participation (need even more room). Compared to sitting on a couch in a small studio with a few friends, it doesnt stand a chance.

The other problem is most peoples first experience is with some shitty mall vr room where the “game” consists of free unity assets slapped together in a way that makes marky marks horizons look polished. Few people start off with something like the half life one.
