Nintendo Life, the delay of Dr Kawashima's Devilish Brain Training: Can You Stay Focused?, as it's leanly titled in Europe, is a strategic one, says Nintendo.
"Nintendo has made the decision to push back the launch date of Dr Kawashima's Devilish Brain Training: Can You Stay Focused? for Nintendo 3DS to optimize the best possible launch timing of this title within the European market," the company told Nintendo Life. "We apologize for any inconvenience this may cause and we hope to announce a new launch date soon."
Brain Age: Concentration Training isn't the only recent Nintendo game to endure a curious last-minute delay in Europe. Scribblenauts Unlimited, originally due in the region on Wii U and 3DS on February 8, is still without a release window; we contacted Nintendo recently for an update but only received the same statement given out in February.
The only update since then came courtesy of 5th Cell CEO Jeremiah Slaczka last month, who posted on NeoGAF to say, "It's been delayed due to some localization standards. It'll be out when that's fixed. There are people working in it. Those standards have nothing to do with inappropriate words or adding 'u's to words to make them British (that'd be insane if that was the reason). It's out on Steam right now in the EU, so if it was that problem, then those words would be in the Steam version."
