huge mistake to give away the first 3 levels or so and then charge. Players get their fix by playing a bit and don't have nearly enough incentive to pay for their rest because there ISNT that much more.
They should have made a paywall for for the game entirely, 4.99$, no free levels (maybe like a 30 second demo try or whatever). Would have brought in so much more revenue
granted I think Nintendo's mobile offerings are simply for advertising and exposure to get people to buy their regular systems. IF that wasn't the case then obviously we'd see Nintendo put something like the original Mario Bros games (1-3) on mobile and they'd sell a kajillion more of that app than Mario Run.
