Tycoon games are about leverage. A good decision at the beginning of the game pays dividends ten hours later. A bad one compounds into crisis. Players who understand how money makes money beat players who grind for it. That economic leverage loop is the tycoon core.

Summer Engine helps you build the business simulation, staff systems, upgrade trees, and competition through conversation. You define the industry and its theme. The AI scaffolds the economic systems that make growth feel earned and crisis feel avoidable with better planning.

The best tycoon games have clear feedback loops: invest here, revenue grows there. Neglect this, customers leave. Players should always know what to fix next. Design your feedback systems so the answer is visible but not obvious.

• Designers inspired by Theme Hospital, Planet Coaster, or Two Point Hospital who want to build their own tycoon.
• Teams building a niche industry tycoon: music label, space station, ski resort, or zoo.
• Solo devs who want a management game with a tight economic loop and satisfying growth.
• Studios targeting the tycoon audience that buys games based on their industry theme.

• Business Loop Prototype

  Build the core economic loop: income sources, expenses, staff costs, and one upgrade path to validate the economic design.

• Scenario Campaign

  Create five scenarios with escalating goals: start small, hit revenue targets, survive crises, and build a legacy-tier business.

• Sandbox Tycoon

  Build an open-ended tycoon with no time limit, multiple industry paths, and deep enough systems to play for 50+ hours.
