Plot hole: During the final battle, we see all the other players charging over the hill and running into battle. We later see that these are just players standing on the streets wearing VR visors. But unlike our hero who is dangling on wires (and used a treadmill earlier on)...nobody on the streets is using any such thing. Which means when they are charging or running, they would all be crashing into walls or any obstacles that get in their way. Certainly nothing like the film.
