Focused, hard work is the real key to success. Keep your eyes on the goal, and just keep taking the next step towards completing it. If you aren't sure which way to do something, do it both ways and see which works better.

At its very core, virtual reality is about being freed from the limitations of actual reality. Carrying your virtual reality with you, and being able to jump into it whenever and wherever you want, qualitatively changes the experience for the better. Experiencing mobile VR is like when you first tried a decent desktop VR experience.

Oculus really started popularizing a new approach using cellphone screen technology, a wide field of view, and super-low-latency sensor tracking. It's not crappy stuff that doesn't work and makes everybody sick. When you experience Oculus technology, it's like getting religion on contact. People that try it walk out a believer.

Obviously, virtual reality is where I've placed my bet about the future and where the excitement is going. At this point, I could say it's almost a lock. It's going to be magical - it is magical - and great things are coming from that. Along the way, I was focused on the first-person shooters. I said we should go do something on mobile.

Developing games for the PC and consoles is all about everything and the kitchen sink. In many ways, you don't have design decisions to make. You do it all. So I enjoy going back to making decisions about what's important as I'm working on a game.

It is a shame that homebrew development can't be officially sanctioned and supported, because it would be a wonderful platform for a modern generation of programmers to be able to get a real feel for low level design work, to be contrasted with the high level web and application work that so many entry level people start with.
