When this got implemented I’d like to see a “Initial season” option in the… options
Never naturally lived long enough to see a CataDDA winter
Probably would need a way to hack and harvest/haul ice or snow for melting to water too…
Another (possibly idiotic) thought is that… don’t most nuclear freezes come from the air being so filled with dust and ash that it blots out the sun almost completely? Was just wondering, because if that were the case then this would probably be better as its own separate (but equally valid/vanilla) mode from the normal game… Just did my research, half-assed, and it is caused by dust and debris, and can also be achieved with a violent volcano (volcanic winter) or asteroid impact (impact winter)… Those two options would the same cold hell, just without the widespread radiation. Also all three events generally involve quite a bit of fire at the start (asteroid the least of which, though it could burn plenty of things under the right circumstances), so there should technically be some pretty bad burn damage in some areas…
Another option, in the generic game, heading north far enough could lead you to the icy wastes instead of it being a seasonal/“time passes” event… But then you could head south and find deserts by that logic (not that Cata’s map is supposed to represent an entire planet, anyway, but it’d serve to add some new biomes).
Anyway, that’s my 87 cents on the subject, to be taken or left!
