Great thing in this "SIM" the crafting system, like the picture below, Craft with Campfire:

To make Fried Salmon, first we need a fishing rod (be crafted by the player) to catch the fish. Than we need to have some luck to catch it.
When we had a fish, we need a camp fire, this need some branches 5 exactly to make the fire place. We add than some "fuel" , again branches min. 15 to make a nice fire.

Now we need also one branch to make the Fried Fish.
