Hobby sims are games about mastery made accessible. Players who have never picked up a guitar can feel what progression toward skill feels like. Collectors who will never afford a rare item can build that collection virtually. The genre is about the joy of the hobby, distilled.

Summer Engine helps you build the skill system, progression mechanics, community systems, and hobby-specific interactions through conversation. You design the hobby and its depth. The AI scaffolds the systems that make mastery feel earned and the hobby feel authentic.

The key design challenge in a hobby sim is translating mastery into mechanics without losing the hobby's appeal. Fishing games that feel like fishing. Cooking games that feel like cooking. Stay close to what makes the hobby joyful.
