Last week, as you might have heard, Dr Kawashima's Brain Training for Nintendo Switch was released on the Nintendo Switch in PAL regions. The title debuted in 18th place on the UK charts in the same week.

What wasn't previously revealed, though, was the fact launch sales of the latest Switch title are "15 times larger" than its 3DS predecessor Brain Age: Concentration Training (also known as Dr Kawashima's Devilish Brain Training: Can You Stay Focused?) in this location.

If you're wondering how it's managed to achieve this, it's all because Devilish Brain Training suffered a severe delay in Europe.

This 3DS title was first released in Japan in 2012 but didn't get a release in Europe (including the UK) until July 2017. That's five years after the original Japanese release, and by that stage, the Switch had been out for nearly six months in PAL regions and the 3DS was beginning to lose its momentum.

Here's hoping the new Brain Training entry for Switch arrives sooner rather than later in North America.
