A lot of people in the community would like to see a wider range of FOV choices. A lot of games usually span from around 90 FOV up to 120 FOV which I would argue is much better. Recently there has been a reddit post going around the community that allows users playing on the steam version of the game to increase their FOV from 90-120 FOV. However, Rare have confirmed that any changes to game files will result in punishment.
There really is no argument to not adding higher fov, like it or not, it would just be useful for everyone. It wouldn't be unfair since everyone could use it, there is no reason at all for it to not be added. Obviously being able to see behind you isn't fair but you should be able to increase past 90.
Hopefully we can get this added because less than 90FOV is hardly ever used by people.
