This is the engine of your spreadsheet. Use this to determine if upgrading your mine is worth the cost or if you should save for a smelter upgrade.

=Upgrade_Cost / Total_Value/sec / 3600

The core of the game. A new spreadsheet must allow you to input your current "Room" levels (Workshop, Forge, Astronomy, etc.) and spit out which planet to buy next.

You start with a single crappy smelter on a barren planet, and within a week, you are managing thirty planets, twelve managers, motherlode mines, space stations, and a tech tree that looks like a spider web drawn by a fractal algorithm.

The spreadsheet highlights which alternate recipes can turn that trash into high-tier items like Navigation Mods or Iridium bars using fewer crafters/smelters. Calculates the "slot savings" of using an alternate recipe.
