I started playing minecraft myself on Xbox360 when it was released. I found it to be exactly what I have always looked for in a sandbox game. It's relaxing, challenging, and creative. with the mode settings you can make it as challenging as you want, even peaceful setting makes it so you really don't have to do anything, you can sit back and explore the game world. After playing for a while, my son became really curious about it (he's 6 now) and mom gave the go ahead to let him try it out. Now, whenever he has a really good week at school he gets an hour of playing minecraft with us. We have it set up so both me and mom can play with him, one playing split screen with him on one tv and the other connected on xbox live in the same world from another console. The updated settings in the game can limit who if anyone else can join in the game online, the difficulty, even auto-save time limits which can give everyone a sort of reminder to stop playing. When he started, my son pretty much would dig a hole and then complain about getting out. We told him to figure it out himself. He now digs entire caves, has built several houses and makes his own tools. When we all play he will say "Hey mom, do you have any metal so I can make a strong pickaxe please?" He uses good manners, great team work, his creativity is astounding. He doesn't like the monsters so we play on peaceful mode. After we play our hour or so of minecraft on saturdays, he will run upstairs, dump all his legos out and play more minecraft in his room, running back down to tell us about another house he built or asking how to build a tower. As with anything, moderation is key, but this is an exceptional game that I believe could benefit kids if used within limits. Once addictive traits come up, i.e. won't go to bed, doesn't want to do anything else but play the video game, then you know it is no longer healthy. This can help develope wonderful motor skill association skills, boost the creative parts of the brain as well as logic, and it is great to play along with your child, then you can directly supervise the activity (it really is fun and challenging for all ages). This is mainly referring to the xbox version which allows more family play such as splitscreen multiplayer and simpler effective settings and player controls.
