While I like the expansion to research, I have issues...
The infinite research thing... I like to finish things. The 20 odd robot follower count is tedious as is, please expand what you mean by infinite research. Knowledge is always ongoing, but in a game, people might not like never getting there.
Now - the things you are using to make science packs with...
For red to green (early) science the study could be of the natural environment. The ores copper, iron, coal and stone, alien plant, soil and water samples. Game mechanics allow for most of this already the soil sample I imagine as a kind of reverse landfill occurrence, a type of (soil) miner gets to a certain depth it's water - which you may fill back in with stone if desired. These lab inputs make so much more sense than current red/green inputs. Trees just get hated on, make em more useful, and easier to harvest, how bout a chainsaw?
As things progress into blue-science and beyond, things like glassware, centrifuges, computers and chemicals might be more useful to a scientist than assembling machines et al.
The military makes sense. We study current tech's use and performance and improve on it where we can - so the weapons for military tech gets my approval
And the 3 processing unit thing - does this come with a 1000 or more science packs price tag for researches? While marathons are all good and well if getting achievements; imo, typical game play shouldn't be an endurance event.
