To avoid minecraft burnout (seasons)

The game is easily (for someone who has been playing for some time) finished, there's no feature that requires days, lots of time to "happen". Maybe season's for biomes, with other dynamics could bright some freshness, like some items dropping only in spring (like flowers for potions), or some meteorological events only happening in certain seasons. All things considered even adding a temperature-bar that maybe makes the player hungry in winter and days longer during summer.
