To be perfectly honest while it’s neat in the rare case when a game attempts to model the body properly in first person.

And in being blunt here. Its a stupid fucking choice.

It makes animations hard as hell to do that don’t cause more motion sickness if not impossible. It makes many actions physically impossible to do in a playable manner. And basically breaks every trick in the book to make things look real.

Remember even in 3d games there’s a LOT of optical illusions and trickiery that has to happen to make things look right.

There’s some bullshit you can pull to give characters a proper body in third person, but it comes with a lot of restrictions that just arnt worth it in most cases.
