Clive Thompson in Wired News:
If Tetris looked precisely like an IQ test, then maybe playing Tetris would help you do better at intelligence tests. Johnson spun this conceit into his brilliant book of last year, Everything Bad Is Good For You, in which he argued that video games actually make gamers smarter. With their byzantine key commands, obtuse rule-sets and dynamic simulations of everything from water physics to social networks, Johnson argued, video games require so much cognitive activity that they turn us into Baby Einsteins — not dull robots.
I loved the book, but it made me wonder: If games can inadvertently train your brain, why doesn’t someone make a game that does so intentionally?
I should have patented the idea. Next month, Nintendo is releasing Brain Age, a DS game based on the research of the Japanese neuroscientist Ryuta Kawashima.
