It's really hard to get into it unless you were there from the early days when there were no more than 50 blocks or so and the game was simple.
It's just like Lego in some respects but digital so with more possibilities. Once you master the basics you can move onto tekkit where you can make nuclear power plants, your own computer systems and automate any tedious tasks but that sh1t is really complicated. It's a good way to waste a few spare hours
A lot of people are put off by the textures but you can change them to HD. I really like the Sphax texture pack.
Also as soon as you're about to get bored of the game Notch releases a big update. A few weeks ago a new boss was released as were witches, bats, beacons etc.
