Back to the discussion on games as a service we had, Nintendo has opened up that the 200MM downloads of Super Mario Run didn't give the profitability it wanted, but the Fire Emblem with microtransactions
The big difference in pricing is that SMR was a free download but $9.99 to unlock the entire game, Fire Emblem was free with microtransactions. I haven't played either, so can't comment on how onerous the microtransactions were. People seem to dig the game, though, I hadn't even known it was out! And I've never played a Fire Emblem. I'm really more interested in the business model.
$9.99 is a steep one-time purchase for a mobile game. I know most of us here keep saying we'd rather pay a higher one-time fee than many small fees, but I'd wager most of us consider $9.99 too high of one. I wonder how the conversion rate would have been at $4.99, and whether that would have increased profitability or not. I wonder how Nintendo would feel about its own premiumness at that price, and how it feels about it now that they've gone free to play.
tl;dr, though, this doesn't bode well.
