Nintendo and DeNA have teamed up to bring Mario Kart to phones with Mario Kart Tour. There's no doubt people will download the game left and right, but a recent report states that investors shouldn't expect the game to pull in big bucks. Takashi Mochizuki of the Wall Street Journal says that Nintendo "doesn't like the idea of players shelling out on in-game purchases and isn't interested in making lots of money from a single smartphone game."
We've actually heard Nintendo make statements like this before. They feel their mobile efforts are more about getting people familiar with their franchises, which will hopefully woo them over to their traditional game releases. While there's certainly some options for Nintendo to make money with Mario Kart Tour, it's not aiming to be the next Candy Crush or Clash of Clans.
