Yes being able to play a game you paid $50 without getting sick is trivial! The whole reason developers cut the FOV is to MAKE people feel claustrophobic, which makes people sick.
A cheap horror movie effect like zooming in really close to a face/person. Then, something extremely obvious in normal sight, seems to pop out of nowhere. Since it violates normal sight and perception it's inept design, just like constantly respwaning mobs.
Personally it doesn't make me sick but the fraudulent design breaks scene and world immersion.
The people can always be brought to the bidding of the leaders.That is easy.All you have to do is tell them they are being attacked and denounce the pacifists for lack of patriotism and exposing the country to danger.It works the same way in any country.
