I get the appeal of Minecraft. That is to say, it appeals to me. I am also impressed and heartened mightily by its success.
But I'm never going to find the time for building 16-bit megacomputers or transcontinental railroads or torching my luxury home. FML, RIGHT.
My first half hour of the Minecraft experience mostly involved:
1) Realising I can dig directly down into the centre of the earth.*
2) Digging directly down into the centre of the earth.
3) Respawning.
4) Constructing a modest house with windows and bookshelves.
5) Digging it a convenient tunnel into the centre of the earth.
You're never more than a few seconds from molten rock, I guess is what I'm saying.
*Similar to my first moments with Fracture, now that I think about it, but with more lava.
