I think you should add a VR portion to this, it's an up and coming platform. As I've learnt today, I suggest including these links:
For Developing:
https://unity3d.com/get-unity
For Learning:
https://unity3d.com/learn/tutorials/topics/virtual-reality
I'd add more, but I'm don't know how to develop for VR, I just know that this is a good starting point.
