From a recent article:

Brain Training dominates ‘08 Euro sales (CVG Online)

- “Overall, four of the ten bestselling DS games in both countries during the first six months of 2008 were in the brain training genre.”

- “According to data released by sales monitor Media Control GfK International, the DS’s heavyweight status in the European console market is closely tied to the popularity of Nintendo’s Brain Training series and other brain training titles.”

- “The biggest demand for brain games is in Germany and Holland”, the company said. More Brain Training was the bestselling title in Germany during the first six months of the year, while Brain Training topped the Dutch chart during the same period.
