You know we can do these things already right? Hard core mode? You know when you die you can delete your game and start a new one. Oh you mean the easy thing, where you eat, sleep and drink? You can already do that. Heaven forbid you can't do it by yourself and need help and someone tell you how to do it.
After all if we really want hard core mode, how about going to the bathroom? After all, eating and drinking, we would need to go to the bathroom or we would die.
So do you really need someone or even worse a gaming company tell you how to wipe?
Power is in your hands. You want "hard core" you can do it. Just takes a bit more effort to tell you that you are hungry, or thirsty or tired. These are all things you can do in the game right now.
