Survival

[Malum Tenebris]

I'm not sure if it's been promised yet or not but I would really like a survival aspect in this game, I believe it would fit perfectly! You have to hunt/buy/gather resources to survive and as long as they're in your inventory you eat them slowly overtime. Not only hunger, but also thirst and rest.

planed, not sure on the need for rest though.
hunting is to get leather.
