The Sims 2: Seasons introduces weather and a defined
seasonal cycle to
The Sims 2. The cycle is determined by players on a per-neighborhood basis, making it possible to have the same seasons year-round or jump between them in an asynchronous order. Seasons and weather both impact gameplay. In summer, winter, and spring, social interactions are more successful between friends, family members, and romantic partners respectively; in autumn, rather than a relationship impact, Sims build skills more rapidly. Lightning can strike trees or Sims, setting the former aflame and potentially killing the latter. Alongside weather,
Seasons adds gameplay features such as gardening and fishing. These allow Sims to learn new recipes, avoid buying food, or resell the products for a profit. Unlike the simplistic flowerbeds in the base game, which only require occasional watering, gardening is based on a complex system where players need to regularly maintain their plants.
Seasons incorporates the talent badge system from
The Sims 2: Open for Business, adding two new badges for fishing and gardening; if
Open for Business is installed, Sims can run groceries or fishmongers.
Seasons is also the first expansion since
The Sims 2: University to add new career tracks, introducing the Gamer, Adventurer, Music, Law, Journalism, and Education careers. Like previous expansions,
Seasons introduces a new form of supernatural Sims. Sims which overuse pesticides can transform into PlantSims,
sprite-like beings with green skin and leaves for hair. PlantSims have different needs and a different lifecycle to other Sims; they age directly from toddlers to adults, and their only requirements are Sunlight, Water, and Love, which function similarly to the normal motives of Energy, Hunger, and Social respectively. They can reproduce asexually, spawning new PlantSims, and receive gold-level gardening talent badges the moment they transform. ==Soundtrack==
