I was at the Game Developers Conference (GDC) a couple of weeks ago. I have to say it was the most productive GDC ever for me.
Not only did I get to "smooze" and talk shop with Phil Spencer (Head of the Xbox Division), but I connected with the combat designer for the new Killer Instinct. He has agree to give me advice and possible direction for Guardian Clash. It was a huge score as far as networking and connections.
The Universal Fighting Engine is being update to work for Unity 5, and soon after work will begin in porting the framework for Unreal Engine 4. Not sure if Guardian Clash will stay on Unity3D or move to unreal. It all depend on opportunities. Time will tell.
