For update 1.1.0:

Because the "research two techs" integration had been described as "boring" (by one person but it was enough) I've changed the industry tech tree's integration of Composite Materials and Advanced Components. The full path is as follows:


-Research Water/Metal or Metal/Electricity 5
-Complete a decision to create schematics for a new building
-Research that building in the tech tree, creating a VERY slow-to-make building that produces one (1) of that resource
-Complete three decisions, each increasing resource production by one (1) and giving you bonus effects (Strategic Bombing Resistance, Plant-specific Repair Speed, and Attrition/Supply Consumption reduction)
-Consolidate your building upgrades into schematics for the completed building, increasing efficiency and output by one (1)
-Research the completed facility in the tech tree, each of which adds five to the production of each building and increases the speed at which you create the plants to "Normal".
