Make surival mode more rich

I think that rather than impossible mode, i would love to have a more rich survival mode, with different challenges that you have to face in order to survive. For example climate change, where you have to make cloths according to the weather, or may be have more torch in your base to prevent you from freeze. Things like this.

I think that this kind changes will help to get more players to minecraft. This will keep players motivated to build better things and will also make the game more fun to play with friends. With this mode we can now share tasks with friends, may be i will build the house and my friends will collect resources to build things for the next climate change, or for the next enemy wave.
