And coming from a place where we're sick of having the thing a month after the first snow fall, I can tell you conditions in most games seem almost idelic *cries*
Anywoo, I really do like snow levels that come with a real banger track and good visual design, Xenoblade 1/2 have great ice caves with incredible themes to go along with. Kirby has interesting design and backgrounds (Star Allies really showed it's HD in all it's glory there). Mario is kind of the defacto representation of what you'd expect from a snow level in a platformer. In DK Tropical Freeze, the last world is comprised of the island from "Returns" but imprisoned in snow & ice which gives quite the view in some cases !
