Hello there everyone......,
I've got level 2 of every Tech 'Aspiration' and Level 3 for Farming and Engineering.
Now, I've upgraded Farming and Engineering to Level 2 in the beginning of the game purely for food sources then waited till I could get Level 2 Science so that I could get Tech Points faster.
So, since upgrading to Level 2 Science, I've upgraded everything else as mentioned above in the first paragraph. I'm now waiting to get Level 3 Science before upgrading the rest... is it worth the wait?? But if I upgrade everything else before getting Level 3 Science, then it would be pointless!! Wouldn't it!!??
I think I'm gonna stick to waiting patiently for Level 3 Science unless someone gives me another strategy.
