Life Sim Templates

Create life sim games with Summer Engine. Get inspired by templates below, or start from scratch with AI.

A life sim is about inhabiting a small world and the relationships in it. You spend your days on routines, build friendships, decorate a space, and watch a character and a community develop over time. There is no fail state to chase, just the steady reward of a life you are shaping.

A template gives you that sandbox running: a character with daily needs and activities, NPCs you can build relationships with, a day cycle, an inventory or customization system, and a place to live. With Summer Engine, the AI game engine compatible with Godot 4, you grow it by describing it: ask for a new townsfolk with a schedule, a gift system that raises friendship, a furniture item to place, or a festival event, and the AI wires the schedules and systems with you while you play days to feel the rhythm.
