Factory Day Puzzle [ended, answers added]

Yeup, today is my factory day, so here's the puzzle.

Prizes are Days Gone, which is current #1 on the community wishlist, and some bundle leftovers.

Since I'm too lazy to make them myself, feel free to share any hints with each others, just don't give direct answers or links.

Oh yeah, Days Gone is region restricted and can not be activated in Japan, sorry

Hint: there is already a hint in ITH description

Just to be clear: you can and probably should give each other any hints/clues/ways for a solution other than direct answers.

At least someone listened.
