I am a huge fan of flight simulation games (and aircraft mechanics in general), and this is a question that has always been interesting to me. Why are some crafts able to fly in super cold areas without freezing over and inevitably plummeting, while others have basically no chance of staying airborne?

They’re designed for it.
They need to use different fluids, or have their systems designed differently. That’s more expensive and less cost-efficient. They may be more complicated and harder to maintain. There’s less demand for planes to fly in those areas, because it’s also less hospitable for humans.
So it makes more sense for normal planes to be cheaper and use simpler systems that work in more average climates, but also have customized planes for the specific jobs that require flying in harsh climates.
