# The Sims Style - Simulation Template | Summer Engine ## About this template The Sims style is the god-game life sim where you control everything from above. You place walls and drag rooflines in build mode, pick countertops and curtains in buy mode, sculpt faces and choose outfits in create-a-sim, then unpause and watch your household try to survive. Sims have needs bars that drain constantly: hunger sends them to the fridge, hygiene sends them to the shower, fun sends them to the TV, social sends them to the phone, and energy sends them to bed. Ignore a need long enough and things spiral. Stack career promotions by building the right skills: cooking for the culinary track, charisma for business, logic for science. Relationships form through repeated social interactions, from small talk to flirting to proposing, and sour through arguments and neglect. Children grow into teens, teens into adults, adults into elders. The story is emergent chaos inside a suburban sandbox. Summer Engine gives you the tools to build this kind of deep household simulation through conversation. Describe your needs system, career tracks, and relationship rules and the engine scaffolds the interlocking state machines that make a Sims-style game tick. You focus on the creative direction: the art style, the personality of the world, and the tone of the drama. The best Sims-style games create stories players never expected. A kitchen fire during a dinner party. A wedding crashed by an ex. A child who inherits the family house three generations later. Give players enough systems and they will generate their own soap opera. ## Who it's for * Designers who want to build a people simulation with deep interlocking needs, skills, and relationship systems. * Creators inspired by The Sims who want their own take on the virtual dollhouse formula with a fresh setting or twist. * Teams building a life sim with generational play, household management, and emergent storytelling. * Solo devs prototyping a character-driven sandbox where player stories emerge from systemic interactions. ## Highlights * ### Household Sandbox Build a single-lot household sim with character creation, needs management, skill building, and social interactions between household members and visitors. * ### Full Neighborhood Sim Create a multi-household neighborhood with career tracks, relationship networks across families, generational aging, and community lots like parks and shops. * ### Build Mode Prototype Focus on the architectural sandbox: wall placement, room detection, furniture snapping, and the satisfying loop of designing and decorating a home from scratch. ## Highlights ### Needs management Six to eight needs bars drain in real time. Hunger, hygiene, fun, social, energy, and bladder compete for your sim's attention every waking hour. ### Build and buy mode Place walls, drag floors, snap furniture to grids, and decorate rooms with wallpaper, lighting, and objects that affect mood and needs. ### Career and skill tracks Sims climb career ladders by building required skills. Cooking unlocks culinary jobs. Logic unlocks science. Charisma unlocks politics. ### Generational play Children grow into adults who inherit the family home. Traits pass down. Three generations of accumulated drama in one save file. ## Features * ### Character creator Full create-a-sim pipeline: body type, face sculpting, hair, clothing, personality traits, and aspirations that drive long-term goals. * ### Needs and mood system Interlocking needs bars that decay at different rates. Mood is derived from need fulfillment, environmental quality, and recent social interactions. * ### Relationship network Romance, friendship, and rivalry tracks between every sim pair. Social interactions raise or lower meters, unlock new interactions, and trigger autonomous behavior. * ### Architectural sandbox Grid-based build mode with wall placement, room auto-detection, roof tools, terrain paint, and a buy catalog of furniture and decor. ## Genre fit * Simulation * Life Sim * Sandbox * Strategy * Desktop * Mobile * Web ## Related Templates [View All](https://www.summerengine.com/templates) [Life Sim Build a life sim where players move to a new place, meet residents, build relationships, pursue skills and hobbies, and shape a life over years of in-game time.
