You didn't watched the video than, because the video clearly explain the disadvantage from first person and how third person make everything easyer
Yeah third person give you more advantage, it's not a question of AI, watch the full video if you didn't, there are technical disadvantage from first persons view, it's not a question of people incompetence, the third person clearly give more advantage
I take battlefront for example because we were talking about how first person game are Easyer compared to third, but it isn't and battlefront 2 is the proof, who care if it's a competitive game or an horror game, first person and third person are equal in every game and first person is alway more disadvantaged and claustrophobic
It also give more tension and fear, take a look at alien isolation in third person, it lack the tension and fear of the first person perspective
