Last week I decided to listen to all the keynotes from Carmack (2002-2013).. So much respect for this man and what he has done for the gaming community.
Definitely would be a shame to lose the yearly keynotes.. Not sure if he will do them anymore as their usually about his research to push idsoftware to newer technologies and improving their games. Maybe a yearly keynote from Oculus VR?
I have a theory that I'd be super upbeat if I had achieved massive, world-class success doing something I love, that was game-changing, in about as pure a form as it gets.
