My thought was that it will discourage pvping to some degree. but not in a negative way. You would have to plan the logistics of long warfare for a large force or plan and build an agricultural ship that can supply the fleet. Which just adds another target during wars. gotta take out the agriculture ship as well as the one with the RN on it. But I see this as just another reason that people wont aimlessly start wars and such which i think people who are not interested in the pvp side may actually like.
My thought on the mechanics on your surroundings is that the suit would house a kind of camel back with water and it depletes at a certain rate at idle and while doing different types of actives it would deplete at a faster rates. The food part im not sure how that would be taken care of. i would assume that you would have to store food in your pack unless its processed into a paste that you drink through a straw in your suit. which honestly doesn't sound great lol
