Apparently this was due to the bad reviews that caused investors to lose faith in the company. So far the negative reviews of the game are mostly about two issues: the fact that it costs a whopping $10 to unlock all of its content, and that it will require an always-on internet connection, something that users aren’t a fan of and in some cases, are reporting quite a bit of data consumption.
That being said despite the negative feedback, it is a pretty significant step for Nintendo who prior to this, had been pretty adamant at not releasing games for mobile. This marks the first time a major Nintendo franchise and character has been officially released on mobile platforms, so even if it is a bust, it does set the precedent for future releases.
That being said, this isn’t the first time that Nintendo’s shares have taken a hit following an announcement. After the Switch console was revealed, the company’s shares also fell by 6%, but hopefully its release will prove their critics wrong.
