# Harvest Moon Style - Simulation Template | Summer Engine ## About this template The farm is yours now. Spring morning: you plant turnip seeds in a three-by-three plot, brush your horse, and walk to town to buy chicken feed. At the flower festival you give a blue feather to the girl who works at the bakery. By winter you are married, the barn holds four cows, and your shipping bin overflows with golden milk and sweet potatoes. Three in-game years later your child takes their first steps across the farmyard. That generational arc, from lonely farmer to family patriarch, is the Harvest Moon signature. Summer Engine handles the interlocking calendars, affection meters, animal mood systems, and child-growth milestones so you can focus on the characters and setting that make your version distinct. Define your bachelor and bachelorette roster, your festival lineup, your crop economy curve, and the engine wires heart events, rival relationships, and seasonal shipping totals. Harvest Moon endures because the romance is earned through daily attention, not dialogue trees. Every brushed cow and watered turnip is an act of care that the game reflects back through friendship points and harvest festivals. ## Who it's for * Devs nostalgic for classic Harvest Moon who want to build a pure farming romance without dungeon crawling or combat. * Solo creators building a cozy farm game focused on relationships, family, and the rhythm of seasonal work. * Teams designing a farming sim where marriage and children are core milestones, not afterthoughts. * Designers who want to explore generational gameplay where the farm and family grow together over years. ## Highlights * ### One-Year Romance Build a complete first year: spring planting, summer festivals, fall harvest competition, winter courtship climax, and a wedding event. * ### Generational Farm Create a multi-year game where players marry, have children, and eventually play as the next generation with inherited farm upgrades. * ### Festival-Driven Sim Design a farm game where seasonal festivals are the main progression markers: cooking contests, horse races, harvest judging, and fireworks. ## Highlights ### Courtship and marriage Gift townspeople daily to raise affection. Trigger heart events at milestones. Propose with a blue feather. Rival couples marry if you wait too long. ### Livestock care and products Brush, feed, and milk cows daily. Shear sheep for wool. Collect eggs each morning. Animal mood and affection determine product star rating. ### Seasonal festivals Each season has a signature festival: spring planting contest, summer fireworks, fall harvest judging, winter thanksgiving. Festivals reward rare items and relationship boosts. ### Generational progression After marriage, a child is born and grows through stages. Late-game unlocks let the child take over the farm with carried-over upgrades. ## Features * ### Pure farming loop No combat, no dungeon. The daily loop is crops, animals, foraging, and town visits. Stamina limits work, hot springs restore it. * ### Rival relationship system NPCs have rival pairings. If the player does not court a character, their rival will. Rival couples eventually marry and have children of their own. * ### Shipping bin economy Drop items in the shipping bin before 5 PM. Revenue arrives next morning. Seasonal price charts and rare crops create a planning metagame. * ### Tool upgrade and rucksack expansion Upgrade tools at the blacksmith using ores from the mountain. Expand your rucksack to carry more items per trip. Each upgrade feels meaningful. ## Genre fit * Simulation * Farming * Romance * Life Sim * Desktop * Mobile * Handheld ## Related Templates [View All](https://www.summerengine.com/templates) [Farming Sim Build a farming sim where players clear land, plant and harvest crops, raise animals, and grow a thriving homestead across seasons.
