Except, video game developers have had like ten years to figure out a VR "killer app" game. Even Valve failed. VR just isn't a significant enough increase in experience for the vast vast VAST majority of games to justify the annoyance of having a mask on, let alone the price. If you are super into simulators, then you have some incredible options, but otherwise it's just a bunch of beat saber clones and mediocre shooters.

VR is a peripheral, not a console. Very few people would choose a VR Magic game over Magic the gathering arena.

Exactly! Even just a small Kojima game exclusive to the Vision Pro would've been interesting.

Kojima is sufficiently famous and well liked to bootstrap a gaming ecosystem, though. They could've gone further and announced an Apple TV Pro, a decent controller, Vision non-Pro (cheaper headset that requires an M1 Mac or Apple TV Pro) and one full Kojima VR game as an exclusive. That could've been enough to start competing with Microsoft and Sony for console games.
