Before you get your hopes too high, Pelikal, Minecraft is
not digital Lego. For that, you need to use Lego's own
Digital Designer platform where you can build everything and anything, never run out of bricks and, if the humour takes you, order instructions to build in real life the masterpiece you've created in your virtual world. It used to be possible to order the entire collection of pieces needed to build the model but that service was discontinued last year; now you have to make your own shopping list and order the pieces in a separate process.
Minecraft it the antithesis of Lego: you start with the blocky world and chip away at it for hours, days, weeks, months on end to create glorious caverns, unearthing treasures and horrors as you go. The clue is in the prefix "Mine"
Beneath it's gaming façade, for those that choose to look, Minecraft is a introduction to computer programming and server management. It has absolutely nothing to do with physical engineering, but applies the "get 'em while they're young" aspect of Lego/Meccano to IT.
And this is what you can do while you're on work-experience!
