Virtual Reality High Level, Platform & SDK

Here is one of many charts to come. In this one I try to include all the current major high levels of VR (Mobile, Standalone, PC and Web), their corresponding Platforms and some of the SDKs to develop with. I'm sure this will be outdated in less than 6 months, but I will update it as I see fit. I hope this aides some of the people in our space. ALSO, this does not include items in China like Xiaomi Mi (Oculus GO counterpart), and Xiaomi VR. If you see any problems, issues or want to add something, let me know directly. Thanks everyone!
