Yes, Brain Training and More Brain Training have together sold more than 30 million copies (according to VGChartz data). This is quite an achievement, and I thought it should be acknowledged. I've searched both the news and the threads, but can find no mention of this historic event.
This puts Brain Training in a very exclusive club of games with sequels that together pass 30 million, joining Pokemon, Grand Theft Auto and Super Mario platformers.
The question would now be, will they make 40 million? And where will it stop?
30 million took almost 4 years, so I would expect that it would take a bit less than 2 more years to get to 40 million, but it is possible.
Good luck, Brain training!
