Why is minecraft so stupid and popular?

I mean its just not the graphics i could play games with bad graphics but its just the objective of the game that really makes me wonder and how this game could be so popular. You just build something then break it build it, break it just repeating itself.

Minecraft is not a game for everybody, some people have different preferences in games. Some like action and fast paced games while others enjoy playing slow peaceful games. But Minecraft isn't just breaking blocks, yes you build stuff and create what you desire but you can also play online with other people. And there are tons of different things you can do on many different severs. So in the end Minecraft isn't just blocks:/
