Seasons

The world will dynamically transition through all 4 seasons, affecting both the visual aesthetic and many gameplay mechanics.

Spring
In early spring, grass will start to grow and sprout an assortment of flowers across the various meadows, woodland and mountain slopes. Trees that have shed their leaves will regrow their canopies. Rivers and lakes will thaw as the daily temperatures rise. Flocks of migrating birds can be seen flying north.

Summer
During the summer months, as temperatures rise, the spring foliage recedes and much of the grass will go to seed.

Autumn
As autumn settles in and the heat subsides, the trees and foliage will transition to autumnal shades of reds, oranges and browns. Dead leaves will blow in the wind as the moose enter their rutting season. Flocks of migrating birds can be seen flying north.

Winter
Winter brings harsh cold temperatures, snow and blizzards. The rivers and lakes will freeze and many species of trees will become bare of leaves. Much of the grass will die or be buried by snow. The severity of the cold temperatures (and heat during summer) are adjusted for easy/normal/hardcore modes. This short video shows an example of a winter blizzard:
