Every time you get a new Productivity module level, your factory ratios change. You're pushed to re-design your factory again and again. Productivity is the original sin of Factorio.
NO MORE!
- Removes productivity modules and compensates through recipe adjustments.
- Removes -productivity tech and compensates through recipe adjustments. Lab and mining productivity research remain.
- Removes Built-in productivity bonuses on Foundry, Biochamber, and Electromagnetic Plant and compensates with extra module slots and recipe adjustments.
Recycling is 100% efficient!
Without productivity bonuses, there is no "positive recycling loop". Recycling returns the materials you put into the recipe.
The end-game factory is just as efficient as before, and your mid-game factory layout keeps working into the late game. You might still re-design your factory for beacons or Foundry, but you don't have to re-design for productivity modules.
