Minimap and food bars are not even close and if you cannot tell the difference then there is no point even trying to discuss the issue with you. We will have to disagree if you cannot see the difference between a magic GPS mapping system with blips for beings versus something your character would innately, intimately, and with a single thought be able to decide. If you can actually tell the difference between the 2 then you are just trolling and purposeful trolling would be rather rude.
Anything you've said while comparing the 2 just illustrates your lack of comprehension of the difference or the level of trolling ocurring. As such, like I said, just have to agree to disagree. Not going to play this out whilst you compare a magic minimap with motion sensors and being/animal identification to something your own body would tell you.
