I disagree, I believe it should have limitless possibilities and I am free to do as I please. I like to use my imagination to enhance the experience of the game. WHile you apparently would rather the game force you to play the role.
Starving to death is a way to force you to eat.
Dying of thirst is a way to force you to drink.
Passing out on the floor or not doing too well in combat is a way to force you to sleep.
It turns out all these things I've mentioned actually affect you in real life and your free will is not so free, if you've been starving for months in real life you will eat just about anything. A video game should force you to eat just like real life forces you to eat.
