Skeleton tracking alone is playable in a lot of titles with the right expectations(PS move service/PSVR level and not WMR/Oculus/Vive level). Most people would be thrilled to be able to play VR with their old hardware/tech for such a low cost thanks to Greg.
The trade off for precision is CPU load for colour tracking. Precision is only crucial for games that requires very accurate aiming: pushing multiple small buttons on virtual console/keypad consecutively, picking things up off the ground, less forgiving shooters like Arizona Sunshine,etc. At this the current state, it is already playable.
That’s my 2 cents after trying skeleton and colour tracking with PS Move controllers 🙂
