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.
