I wasted entirely too much of my life on the PS2/SNES version of HM, I am going to steer clear of this. Not because it's bad, but because I might spend another large chunk of my life playing it, to the detriment of my health, my social life, and my sanity.
Having said that, two of my friends are playing this and loving it. One of them has called into work for the past week to play it from the moment he gets up til he goes to bed, only stopping when he realizes he's starving or dehydrated. The other is disabled, and she hasn't forgotten to eat yet, so she gets a pass I guess.
