for game development apparently godot has a standalone version for Meta headsets, but it doesn’t really work on the Vision Pro other than some community version that only allows it to display 3d models in small bounds because of OS restrictions, theoretically it should work immersively with WebXR but I don’t really know (and then you have to limit your game to what can feasibly be downloaded in a few seconds)
Did they make money? obviously not.
Will it help them make money in the future? nobody knows. Probably not as much as it could have, we’ll have to wait and see.
