I think it would be great to have a way to limit the range of how far a player can see in ft. so that for example if a player is in fog they can only see 5 ft. The only way I see to make this currently is to take players night vision and lanterns and such away and make them emit 5 ft of light, which takes a bit and interrupts the game flow, so an additional option for this could be added under the Limited Field of Vision which limits in degrees. I saw a different post about something like this but it didn't get enough attention to be considered so I thought I'd open up a new one.
