Sure and a good majority of them are 2D or using art styles that have the lower production costs(space sims excel at this for instance, House of the Dying Sun being the latest great example). Once you go 2D -> 3D you have to worry about: Matrix math Import pipelines Skeletal animation and skinning Perspective, z-buffers and z-fighting Culling, LoD, etc Texturing, mipmaps and shaders and more... From a technical perspective I think it's totally a cool thing. However from a user perspective it's normally a net-loss. As someone who's been in the 2D/3D IxD space I'd love for it to be the other way around but sadly it's not. I do think there are areas like architectural and space visualization where VR could be compelling but that's a small market and probably not something we'll ever see at 'web scale'.
