Well, that’s not a bad reason on it’s own. Not to mention that a snowy location would be a good change of pace when almost half of the destinations are rather sunny and warm places, and it could allow for some unique kills, opportunities, gimmicks, just to name a few ideas: snow piles that can be used to hide bodies, stash items or create snowballs; icicles and piles of snow on the roofs for falling object accidents; ice that can function as a slippery surface (banana/wet floor from Bank) or as a trap for targets (crack the ice so they would drown)
