Serene Seasons, released in 2018, is a game modification that fundamentally alters the environment by introducing a dynamic four-season cycle: spring, summer, autumn, and winter. The core gameplay loop requires players to adapt resource management and agricultural planning around these seasonal shifts, as crop growth and weather patterns are directly influenced by the current time of year. Distinct visual changes accompany each season, including altered foliage colors and the introduction of snow in winter across various biomes.
