Super Mario Run downloaded 78 million times; more than 5% paid for full version: Nintendo president— Yuji Nakamura (@ynakamura56) January 31, 2017
Though impressive on the outside, it looks like Nintendo aren't best pleased with the result as the total number of purchases sits at about 4 million. Even with such a large number of purchases, this 5% conversion rate means that Nintendo actually fell short of its aim.
Yuji Nakamura reported the figures earlier today and went on to state that Nintendo's president had expected conversions to fall in the double digits, so only achieved half of their original goal.
Nevertheless with the Switch peaking over the horizon and Super Mario Run's Android launch incoming, there's plenty of things to tweak the figures in their favour.
