here are some additions EA can add to seasons

More Seasonal Events
Seasonal Festivals: Expand on current holiday celebrations by adding region-specific festivals, such as a Spring Blossom Festival, Autumn Harvest Festival, or Winter Snowman Parade. These could feature new activities, foods, and decorations tied to each season.
Weather-Specific Holidays: For example, Snow Day during winter where Sims get to enjoy winter activities, or a Rainy Day Holiday in the spring where Sims can stay indoors and enjoy cozy activities.
2. Natural Disasters
Disaster Mechanics: Introduce a variety of natural disasters that can occur based on the season, such as hurricanes in the summer, tornadoes in spring, wildfires in autumn, and blizzards in winter. These events could disrupt gameplay but also offer new challenges and opportunities to rebuild.
Disaster Preparedness: Players could take preventive actions to prepare for these events, like reinforcing buildings or creating storm shelters. Sims could also have new careers or skills focused on disaster relief and preparation.
3. Expanded Gardening and Agriculture
Farming Overhaul: Add more complex gardening mechanics like crop rotation, seasonal crop varieties, and the ability to grow more exotic plants. For example, add specific crops that only grow in certain seasons, like pumpkins in autumn or tomatoes in summer.
Greenhouses: Introduce greenhouses where Sims can grow crops year-round, especially in the winter, protecting plants from the cold. Greenhouses could also offer customization options to make them more stylish.
Pest Control: Introduce pests that damage crops in certain seasons (e.g., insects in summer, mold in spring), requiring Sims to take action like using sprays or natural remedies.
4. Dynamic Weather Effects
Temperature Sensitivity: Add more realistic temperature effects on Sims. For instance, during extreme heat in summer, Sims could suffer from heatstroke, while during winter, they could experience frostbite or hypothermia if not properly dressed.
Frost and Snow Accumulation: Introduce more immersive snow systems, like snow accumulating on roofs, lawns, and pathways. Sims could have to shovel snow to clear paths, and roads could be icy, affecting how they get around.
5. Environmental Impact
Seasons Affecting the Environment: Introduce a mechanic where Sims can see the impact of the changing seasons on the environment, like rivers freezing over in winter or flowers blooming in spring. Sims could plant trees, which could affect how the environment looks as the seasons change.
Climate Change System: Introduce long-term gameplay consequences, where the weather and seasons can change over the years based on Sims' environmental actions, such as excessive pollution or excessive use of pesticides in farming. This could lead to longer droughts, wetter summers, or more severe winters.
6. Seasonal Clothing and Fashion
More Seasonal Clothing: Expand the clothing system with more diverse seasonal outfits, like warmer layers, winter coats, and spring or autumn-themed fashion. Sims could be affected by the season and would need appropriate clothing.
Fashion Trends: Introduce seasonal fashion trends that change each year, encouraging Sims to update their wardrobes to match the latest seasonal fashions.
7. More Weather-Related Activities
Weather-Based Jobs: Introduce new career paths or skills that are directly influenced by the weather, like meteorologists, storm chasers, or snowplow drivers. These careers could become more relevant during certain seasons.
Seasonal Outdoor Activities: Add more interactive outdoor activities tied to the weather, like building a snow fort in winter, making a snow angel, or rain-themed activities like puddle jumping or indoor gardening when it’s too wet outside.
8. Dynamic Seasonal Decor
Seasonal Home Customization: Add more options to change home decor based on the season, like themed furniture for each season. For instance, in the winter, Sims can decorate with Christmas trees, stockings, and warm, cozy furniture, while in the summer, they might opt for bright colors and outdoor furniture for barbecues and parties.
Seasonal Gardens: Sims could plant seasonal flowers, shrubs, and trees that change colors as the seasons pass. New flower varieties could be introduced based on the season, like tulips in spring, sunflowers in summer, and chrysanthemums in autumn.
9. Life Events Tied to Seasons
Birthdays and Life Milestones: Add more customization for birthdays and other life events so that they can be celebrated in different ways depending on the season. For example, winter birthdays could involve snow-themed decorations, while spring birthdays could focus on fresh flowers and outdoor parties.
Seasonal Affective Disorder (SAD): Implement a system where Sims can suffer from SAD in the winter months, leading to mood swings or needing therapy or sunlight lamps to cope.

New Cultural Celebrations: Introduce more international holidays to reflect different cultural celebrations tied to seasons, like Diwali in autumn or Cherry Blossom Festival in spring, which could offer new decorations, food, and activities.
12. Interaction with Other Expansion Packs
Linking Seasons with Island Living: In the tropical climate of Island Living, weather patterns could be different, such as hurricanes and tropical storms in the summer months. Players could prepare the island by reinforcing structures or moving inland to avoid flooding.
Linking Seasons with Cottage Living: Seasons would directly affect farming in Cottage Living. For example, after a heavy snowstorm in winter, crops could be ruined, or after spring rains, new crops would grow faster.
Linking Seasons with Get to Work: The change in weather could impact Sims working in careers like retail, science, and medicine, with certain conditions affecting business hours, work environments, or equipment.
