So what are the odds of HL:A or Udon being powerful enough to make your asset flip FPS game you can take baby-step grow and just apply what you see in the tutorials to enhance user interaction and content?
I'd like to believe I made a good attempt at trying to make a game in Unity, but the fucking thing is like piecing together a jigsaw puzzle with missing elements. Not only you piece the jigsaw, but you must find out which elements are missing and know how to order/make new ones to fill in the blanks. I'd end up spending months if not years of my time just to get shit-tier firearms interaction that would probably be worse than what Anton shits out in a week.
Even learning Blender is easier than making spaghetti code when you don't know nothing about it.
