Although I am unsure of where all of this narrative comes from, it's so good it nearly brought a tear to my eye:
Nuclear Fruits https://youtube.com/watch?v=15dxuAbTC0A&itct=CBQQpDAYBSITCJS...
Origins of open worlds: https://youtube.com/watch?v=EdV_2svrDVc&itct=CB0QpDAYAiITCK_...
I highly recommend watching all his feature videos.
