Various methods of preserving meat for future use have always been on humanity's radar. In The Long Dark, as in real life, things spoil. It's an essential mechanic, so you cannot hoard 100kgs of bear steak under your bedroll and call it a day...or two months. The thing is, it would be great to have some method of meat preservation in place - spending some time to dry out/salt the meat, so it lowers the weight, but makes you thirstier after consumption.
Additionally, the weather never reaches above zero temperatures - therefore it should be possible to stack some steaks in an outside container and have it never deteriorate - as shelf life of raw meat is measured in months. The downside - for balancing reasons, obviously - you would have to thaw the meat before consumption/cooking, essentially providing the player with another challenge - the need to plan thawing your meat day the day before being able to use it in any way.
It's just an idea, what do you think, guys? Let's brainstorm.
