"Congratulations, Technician, for discovering the recipe for your first Generator, you have made a valuable contribution to my research, and for that, Humanity/Ponykind is starting to look up to you."
Wouldn't you be encouraged to push on by opening a book containing this passage, when you craft your first generator? What if you got a similar message of praise, when you create one of each machine? Would you press on in the name of Science, Technology, Engineering, and Mathematics?
The thing is GregTech doesn't praise and encourage players for crafting machines of the Bronze Age, and beyond. You may know the recipe and struggle for your first small coal boiler, but do you gain something for your initiative? NO! You just craft a piece of junk, without any clue on how to use it without killing yourself.
Greg, I suggest that you give players a token of contribution in the form of writing. Operator's Manuals for each machine, with a word of praise in the beginning. Perhaps something witty to compliment the Machine crafted.
