In my opinion, the personal threshold of 'making' says more about the remnant era in which you were raised in rather than about the specificity of the act itself?
Your grandparents lived in an era where it was common for men to build their own homes.
Your parents lived in an era where it was inconceivable for a piece of furniture to not come fully assembled in their per-fabricated home.
We now live in an era where homes are made in mass scale and we assemble our own furniture. Did I make an IKEA table? I don't know. I paid for it, drove it home, and assembled the machined parts and added the same size Allen key to my collection. It's certainly not a table without my contribution. But I couldn't have built it myself from scratch.
I now tell the computer with the magic words please and thank you because I skimmed a research paper saying it'll be more cooperative in completing my tasks.
Did I make a game in unity where I just mishmoshed the preassembled assets together? I don't know. The only difference between IKEA furniture and my game is the permutations of my asset combinations, really.
