We like what DIY.org says about Minecraft (a game our kids are obsessed with, though we don't really get it).
"Many people working in tech today got their start building with LEGO and SimCity. Today there's Minecraft. Using blocks, kids can build just about anything in a virtual world. It’s being used in classrooms all across the U.S. to help kids discover engineering concepts, geography, architecture, mathematics, as well as critical thinking skills and teamwork."
