I don't fault you at all but I find this post rather disturbing. In geological history there have been long periods of place your times where glaciers grew to large extents. And the Holocene is a time when these glaciers have retreated a lot and that has been over a period of 10,000 years and we are due to have another Ice Age Again. So your game might be a little bit too real in a few years.
so i should play it more, to get ready..? or not play it, because of..fear? what are you saying?
Well, does the video game really prepare you for an deep-freeze world? Extreme climate change seems far more likely to take the form of a deep-freeze than global warming. Perhaps we should also learn how to forage for food. Learn to trap and catch game. Perhaps the game can be good for you but only if you also put the foraging and hunting into real practice because the game doesn't capture everything.
