Plot hole: In all scenes where special or heavy items are used against the sixers, they are 'zeroed' in waves or circles. This can be seen by their stations turning red in clusters. This makes no sense as the stations have fixed positions, meaning that the sixers would have identical positions in the Oasis and have no freedom or own will to move relative to each other.
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.
Suggested correction: How much you have to move in the real world depends on how much and what kind of haptic gear you're wearing. If you have a boot suit and an omnidirectional treadmill, for example, you do all your own walking, running, and jumping, because you have the space to do it and the haptics to respond to your movements. People with minimal gear-like those we see on the streets-might have only a visor and gloves, say, and they have to do all their "running", "fighting" etc. with signals from their hands. It's like if you don't have a joystick, you have to use the arrows on the keyboard.
I disagree with this. At one point during the big fight you see a group of players as Spartans running along the street, with visors on. They definitely would have run into a wall or other person at some point. I'm sure they were not the only ones. I'm sure it's possible to use something for movement control besides actual physical movements but that scene shows not everybody is using it and there should be a lot of accidents with people running into things and each other. At the start of the movie you see a mom climb upon her couch to imitate climbing up a rock in the game, physically imitating the movement. The lack of showing this disability for players on the streets might not be so big as to be a plot hole, but definitely a factual error.
Here's a clip of the Spartans https://youtu.be/D_eZxSYRhco?t=1m36s that shows they are definitely moving in exactly the same way in the Oasis as they are in real life, so even though yes it would make perfect sense for there to be different control schemes depending on the level of technology a person has, the film appears to show that it's a one-to-one translation of movement regardless of practicality or safety.
I don't think it's an issue. Note that several times in the movie people are also shown to be playing the game while just sitting down at a table. Case in point, the guy that dies on Planet Doom and then immediately jumps up from his work desk and tries to run to the window to jump out. He was sitting down but still playing in the PVP on planet doom. Same is true for right as Wade is telling that when you die all your money and everything you work for is gone. The scene shows Sho stabbing a person's avatar on Planet Doom that then shows the person who was playing that character falling out of a chair he was sitting in. With another person sitting across from him also in a chair.
I think in the end we can all agree its a mistake in the movie but not as big as a plot hole. Some people running, some people sitting down whilst playing, could be a matter of taste, but the Spartans running across the street with a visor on is definitely not logical.
The players have the ability to see the real world because the glasses of most people are transparent, Art3mis even looks at Sorrento approaching in IOI, which Wade even asks why she is looking in that direction if there is nothing there, so the players would not hit the wall when running.
Revealing mistake: Just after Wade gets threatened and his home is about to be bombed, he leaves his van trying to call his friends. After this shot, the camera pans over a load of scrap cars. Whilst the movie is meant to be set in America, at least 3 UK registered cars are visible in amongst the scrap cars, still wearing their UK plates. These 3 rather unremarkable cars, a Ford Mondeo, Fiat Punto, and Ford Fiesta Courier van, are unlikely to have ended up in the US.
Suggested correction: Though unlikely, not impossible. This is a future scenario and it's not far fetched to think that some economic crisis prompted people to buy import cars and then never given US plates. Or they were imported for parts. Or some UK workers using their own car.
Suggested correction: From a military point of view it makes perfect sense. AOE weapons would be most likely to hit members of the same squads, companies or battalions. It would make sense for squad mates in the oasis to stick together in stations as well. I just watched that scene. As long as the Sixers are trained soldiers or players it makes perfect sense.
