Adds three upgrade levels for most basic game entities and recipes. The upgrades are either buffs to entities or upgrades to basic component recipes.

For example you can upgrade a stone furnace to be faster and create less pollution, or you can upgrade the iron processing recipe to produce 50% more iron, but take twice as long to smelt.

The first recipe upgrade is cheap, just costing basic science kits.

The second recipe will cost special science kits based on the upgrade. If your upgrading the stone furnace to study stone, if your upgrading iron processing you need to study iron. As a result this mod add a lot of science kits.

The third is really expensive.
