Quick Answer
Blue science is not one recipe; it is the point where weak smelting, green circuits, oil, power, and bus spacing all become visible. Stabilize those before scaling labs.
Readiness Table
| System | Ready when | Warning sign |
|---|---|---|
| Smelting | Iron and copper lanes stay fed | Belts starve when science starts |
| Green circuits | Dedicated copper and iron input | Every build steals from the same trickle |
| Oil | Petroleum, plastic, sulfur are planned | Pipes exist but no product flow |
| Engines | Steel, gears, pipes have a lane | Engine build drains the mall |
| Power | Steam or upgraded power has margin | Brownouts during oil startup |
FAQ
Should I build a perfect main bus first?
No. Leave space, keep lanes readable, and fix bottlenecks as blue science exposes them.
