Is there for example a programming language for editing videos or creating 3d models?

Well, I'm quite lazy as a person, so I have a lot more of not yet started projects then not finished ones

Oh yeah, I also know about esoteric languages, but that's should be it

I already know about this game, and I even mentioned it in the post

Hm, alternativeto says that grayjay is proprietary

But it doesn't seem to have it's source publicly available

Thanks for the notice, the .ml were seen suspicious to me earlier, especially when I saw the last thing I was supposed to write in the ancet field or whatever it was called

By in-game manual I meant a manual which built directly into the game and a main character could read it, not just a player who opened a PDF outside the game. And also usually those manuals are stylized, like in papers please (which I forgot to mention in the post btw) or like in Uncle Chop's rocket shop

Okay thanks
