Brain Age 2 review at Nintendo World Report.
"It's been about 17 months since I reviewed the original Brain Age, commending it for being the first non-game to actually hold my interest. I really enjoyed its pick-up-and-playability, simple-but-fun activities, and of course, Dr. Kawashima's quirky, disembodied head acting as your mentor. So I had high hopes for Brain Age 2, and while it brings the aforementioned to the table, I can't in good conscience award it the same high marks.
Once again, Kawashima, renowned Japanese neurologist, leads you through various tests to determine your brain age level, followed by a set of hurdles (completed via the touch screen or microphone) meant to quicken your ability to call up information, improve your memory, and generally, whip your mind into shape."
