Wait, wait, wait...let me get this straight. You have a serious interest in game development, have been planning a big FPS project for years to the point where you even invested money to get your IP copyrighted, you're working together with professional game developers - but you've never heard of Unreal Engine 4 before this video? Dude, I don't want to sound condescending, but thats just strange.
