Completely new quests to progress through. New items and creatures befitting colder climates. How about a snowshoe hare? Snowfall covering your garden. Mostly as a cozy treat! Unique temperature-based expansion mechanic. Rely more on keepers who have distinct jobs. New upgrades specific to the world. Can be accessed from your existing save file. Achievements, of course. Most items and creatures will find their way back to your main world.
