 As mobile gaming grew, Nintendo was criticized for not taking risks in this area, prompted when the valuation of GungHo Online Entertainment, the publishers of the financially successful "Puzzle & Dragons", exceeded that of Nintendo's in June 2013.These concerns were also compounded by lower-than-projected sales numbers for the successors of Nintendo's consoles, the Wii U and Nintendo 3DS, which had caused Nintendo's stock price to drop.In an interview with "The Wall Street Journal" during E3 2013, Nintendo's president Satoru Iwata addressed the lure of developing for the mobile market, but had opted to not take Nintendo in that direction, focusing instead on providing compelling games that would drive their hardware sales, retaining their unique approach.
