Factory games produce a specific kind of satisfaction: the moment when you step back and watch a machine you built run perfectly. Iron ore comes in, gets smelted, turned into plates, assembled into circuits, packaged and exported. You built that. Now you need to do it ten times faster.

Summer Engine helps you build the resource nodes, production machines, logistics networks, and scaling systems through conversation. You design the production chain and the end products. The AI scaffolds the systems that make automation feel like engineering.

Factory games reward players who think in systems. The best moment in the genre is realizing you designed a bottleneck five steps ago and now need to trace back through the whole chain to fix it. Make that debugging process satisfying.

• Designers inspired by Factorio, Satisfactory, or Shapez who want to build their own factory automation game.
• Teams building a factory game with a specific setting: magic, space, medieval, or organic.
• Solo devs creating a compact factory game focused on elegant production chains.
• Players who love automation and efficiency optimization as gameplay.

• Production Chain Prototype

  Build a 5-step production chain with raw resources, two intermediate products, and a final output to test the automation feel.

• Campaign Factory Game

  Create a campaign where players unlock new machines and resources as they scale, with goals driving the progression.

• Freeplay Factory Sandbox

  Build an open sandbox with a full technology tree, all resources, and no goal except the player's own ambition to scale.
