Hm... so we're adding a mechanic that will make people not want to go out at night in the early game? Isn't that opposite what they wanted? Start in the forest and always be dealing with colder temperatures (why is the forest cold in Arizona?) and have it be even worst at night, making you move more slowly and use more food? Why would people bother going out at night at that point? Food can already be a challenge for some people in the first few days because the animals in the forest can be hard to see, so now you're going to use a lot more food... what was it? 300% and 600% more? And you'll move slower. Alternatively, you stay at your base all night and not deal with it. You can't carry a torch and fight at the same time, so you have to either not be ready for a surprise attack (which will happen more often with smell) because you're holding a torch constantly or else you have to keep dropping them and stand in place next to it until you warm up or you have to keep swapping back and forth with your weapon. Sounds like more of a nuisance than a benefit. Cold in the snow and also in the desert at night makes sense. Heat in the desert or even the burnt forest (from fires) makes sense. Wasteland could be either/or. But making the forest too cold doesn't make much sense, especially in Arizona.
But I suppose some people want to struggle for everything. Unfortunately, there hasn't been any mention of being able to disable temperature without using a mod. We'll see how it works, but it sounds like it'll just make the early game more annoying (I already don't enjoy the early game). Guess I'll probably have to mod it in some way - changing biome temps, or automatically giving me stuff to be warm in the forest when the game starts so I don't have to deal with it, or some other thing that makes it less annoying.
In the end, the food (cold temps) and water (warm temps) don't bother me too much, but I already hate being slowed down by things like a sprained or broken leg, so being slowed down by temperature really doesn't work for me.
