Daughter is 9.
First we got it for XBox1.
Then she started watching Minecraft videos on YouTube where:
1) Several people are playing the same map at the same time.
2) On cool maps.
3) With awesome mods that allow things like realistic furniture or building something by pressing a button, or whatever. Command blocks?

So I plopped down another $27 and got it for her PC laptop, but it doesn't seem to allow any of that stuff.

What do I need to do to make that possible?
How much money are we talking about?
Will any of it require serious computer skills?
