This is an amazingly powerful construction world - imagine video legos on steroids. My scientifically inclined 8 year old has learned to build buildings, ships, railroad systems, elevators and more importantly had to solve circuitry, structural and mechanical engineering issues in the process. Just fantastic.
I would like to know however, what the risks are of the user additions - specifically these "mods" which I understand are modifications and enhancements that other users develop and can be downloaded and installed. This appears to be a fairly complicated process, and seems potentially fraught with hazards. On the other hand, learning from other people's models seems to have a lot of potential benefit. (and my kid won't leave me alone about them....) I was hoping a trusted organization like common sense media might have delved into these issues. Any feedback from more experienced minecraft parents? The game itself is fantastic and more or less safe for mid-elementary school on (unless you object to creepers and zombies).
Inevitably however, kids will want to go to youtube to see other models and tutorials on how to build projects (their friends will tell them all about them) and that is where we run into difficulties. Some tutorials are great. Some are completely inappropriate for young ears.
Also the multi-user settings scare me, and we have steered clear from there.
Overall - highly recommended, but must come with some serious limits for younger users.
