Kantan Games' Toto said investors should "manage their expectations to some extent" as the initial launch of Mario Kart Tour has "a big minus" that is core to the game's popularity — the lack of a multiplayer mode.
"There are tournaments inside the game, right? There are leader boards inside the game, and ... you cannot play against your friends," he said. "I think it is a little bit ridiculous."
"I think it will dampen the reaction, I think that, you know, some people might complain. And I think that ... it might also hurt monetization to some extent," Toto said, as consumers will likely be "more motivated to spend money" if they can play with their friends.
Still, he said the number of downloads for the game will likely be "through the roof" and it will still "be a hit" nevertheless.
