That's largely what the game was based off of!
I'm guessing you mean "What is the secret recipe Notch mentioned in the interview?", and the answer is "Nobody knows." That's why it's still a secret. He did say that it was pretty simple and not really worth more than 5 minutes looking for, though, so don't sweat it.
notch used programming which i have no idea how to do but long minecraft commands are pretty much the same thing.
No idea. However, you can follow notch's twitter and stay updated on his progress.
Notch was the person who got the original idea for Minecraft and leaded the developer crew, but the developers are 4jstudios and Mojang. Also, Notch gave Minecraft over to his friend Jeb, who has been running it for quite some time now.
Not officially, but minecraft YouTuber SwimmingBird made up his own idea on the origin of the fabled Steve. Open up youtube and then paste this behind it on the url bar. /watch?v=vwSb2MTjiOg
Leading of them - top-notch idea
At first he didn't like them, he didn't really like the idea of his creative vision being modified. But he has tried out various mods and completely changed his mind, glad his creation has inspired people to make things for it.
kindness of its creator
I have no idea why
They can if the developers see it and see it as a good idea.
no
That's a pretty good idea. Maybe you should email or talk to Notch or Jeb about it somehow. Or you could post it on some kind of blog, and if it gets popular enough, it could be in. That's pretty much the way it happened with carrots and potatoes.
