I used one of those 3D printers to create a shield and it's pretty legit. Like its sturdy, I straight Kenny Griffey Jr.'d it with a baseball bat, and it only made a dent.
Which made me think, if they have someone get the game to print the virtual reality in some way. It's hard to explain but I can picture it. Like copy and paste but portrayed in the headset? Anyways..
I know though the matrix and SAO type won't happen, unless humans evolve towards taking the consciousness and putting it in a robot body. For that to be in a video game, grand things would have to happen in humanities evolution. Honestly with how things are going, I don't know if it will last that long.
