It gets way easier for "feel" of weather too! In most habitable places in the world, 0°C is around as cold as you'll regularly see (also a handy number for when you need to watch for ice). Similarly, 40°C is around as high as most habitable places get, also a nice easy number to work with.
In fahrenheit, these numbers are 30 and 105, I mean I can get rounding down for ease of use but you're moving the reference points a lot to make it 25 to 100 for what you usually see and that's certainly not more intuitive than 0-40
DRM takes away from development budget (it isn't free). If they are charging me for the experience, I don't want to fund something that, best case, detracts from my experience using the product. If there were an actual argument that the drm would prevent developer losses (I'm willing to ignore the overwhelming data suggesting piracy, in fact, leads to increased profits), I'd be somewhat sympathetic, however this is an online only, co-op game that requires server handshakes. There is not even a hypothetical benefit to invasive DRM, so why would I agree to pay for it?
