first thing to build.

So everytime I start a new world I usually need a lot of stuff, you know, diamonds, stone, coal,...

What I usually do when I start, is making a huge unground tunnel in my house. This way I have most of the resources I need and a safe and easy transportation way if I'm tired of the place my house is now.

 

So it starts with just a huge stairs going down. 

Then a railroad, so I'm faster downstairs.

Downstairs, I have a small room with some basic stuff so I don't always have to go upstairs again.

If I stay on the rails I end up in this huge tunnel that brings me to the other side of this world.

On the other side I put enough launchers so I don't have to get out of the minecart.

 

And here we are.
