Intro worlds/ Turorials

I see that, even if you are old enough to see the legacy version of Minecraft: If you don't see the tutorial world before, you never care about Minecraft at all to this day. And to be honest, a YouTube video doesn't show me to good are the actual Minecraft. So like, Mojang just put on there for what? What's the magic? What is Minecraft? 4Jstudios always know this and make those giants world justo to make the player play it even for their life, or the theme world of movies or games, like think of achild that doesn't see something amazing on Minecraft just because you don't know even what to do after 10 or 20 minutes. Like sme with the 2 weeks Minecraft Phase.
