I think campfires if added should have a burning mechanic so if you get too cold you could warm up
Stage 1: starting the fire would need a mini game to light it up burning the wood in the fire, small fire til it grows but if your right next to it you will warm up
Stage 2: burning but still not as big as it can be, you can stand further away but you might need firewood on standby
Stage 3: all the wood in the pit is burning and you can go a reasonable distance we’re the heat from the fire warms you up, this is when you chop trees to feed the fire.
Stage 4: fire looks like stage 2 but you will need to add more fire wood in order to get the fire back at stage 2, you will have to do a mini game to push the ashes to the side so the fire has enough air at the bottom.
Stage 5: burned out. All the wood is white and the fire is now just smoke.
