Ok, before anyone starts to laugh, NO not those parts. Now..one of the things all games I've seen so far have in common is this: they want us to accept, gladly, that we are NO LONGER human. That we can run across vast deserts without water, or swim for ever breathing water and never drown. Or run across continents without the need of food or rest. If we all accept that, then congratulations...your a cyborg or worse, but definitely NOT human. A person, military or not, needs food to keep his health up, and rest every so often, no, he doesn't need to sit still or lay down for 8 hours straight, but some rest is needed, so why not a 5 minute break every hour or so to grab a bite to eat and refresh our body's? I understand people in games want to feel invincible, well then don't pretend to be human..lol. If you want to truly show the humans trying to make it on some alien world, then show them as we are, only in really good condition, there's not a single one of us here that can run for an hour or more without rest, so why make it seem that to get to a star to explore, we need to give up humanity for some machine body or something. It doesn't mean we need to die if we overdue it, but maybe have our health drop to a lower level because we aren't taking care of ourselves, something like that.And no "potions' if I wanted to live on those I'd play Wow, this is the future, food can and will be carried for long times without going bad, but sooner or later, you'll be away from camp and run out of food, so eating fruits and berries would keep you going until you make it back, but without anything, you'd be a sorry looking case in a day or two without food.
