Business sims are about strategy at scale. Players are not managing individual tasks, they are setting policy: pricing strategy, hiring philosophy, product roadmap, market positioning. The business runs itself based on the decisions made at the top.

Summer Engine helps you build the market simulation, organizational systems, financial model, and event chain through conversation. You design the industry and its competitive dynamics. The AI scaffolds the economic simulation that makes good decisions pay off and bad ones compound.

The best business sims make players feel like real executives. They see the financial levers and know which ones to pull. They read the market report and adjust strategy. Design the information displays so players feel informed, not overwhelmed.
