So is Minecraft really all that?
I was always into computers, writing programs in BASIC on my Commodore Vic20 when I was barely old enough to read/write. When my son showed little to no interest in computers, I was disappointed but supportive in endeavors he did seem to enjoy which had corollaries to my obsession w/computers such as lego, puzzles, engineering, science, etc.
When he expressed interest in Minecraft, I was admittedly skeptical as I see most kids just playing it as a game. However, my son uses it like computer Legos, building shit over and over again and exploring the virtual world of a 6 year old.
Starting with this, I hope he continues to learn about items which interest him through his directly manipulatable world just like I did through my own when I was his age. While like any tool may not be the best for every child to learn, it has begun to pay off and allow him to grow and develop educationally w/o him wanting to play it only as a mindless game.
So no, it's not "all that" but it's certainly better than him watching TV or only playing games on a tablet or game system.
