Making the brain do things so that it can do related things better is a pretty good and well-established idea. Doing lots of basic math really can help you with the hard stuff and keep your brain working better. Nintendo has turned this idea, and the research that inspired it, into a cultural phenomenon and system mega-seller via the Brain Age series. Since this is the video game industry, if one person leads, many others will follow very quickly. Electronic Arts took a surprisingly long time in developing Brain Training for Dummies ... and unfortunately, the effort that may or may not have been put into the development effort doesn't really show. As a piece of software, it is decent, but as a game and as a brain training tool, it is surprisingly limited and rather boring by design.
