'Mario Kart' is finally coming to smartphones - here are 5 things we know (and don't know) about it

Smartphones are powerful enough to run many console games. In many cases, though, games are built for use with gamepads — smartphones have the horsepower, but not the hardware, for games that require intricate controls.

Thus, in the case of "Mario Kart Tour," it's likely that the game's controls will be pared down significantly from what you do in "Mario Kart 8 Deluxe" on Nintendo Switch.

The core loop of "Mario Kart" is racing (accelerating, braking, drifting, and jumping) and fighting (using power-ups gathered during the race). It's possible that Nintendo will require players to hold down a virtual button on-screen for gas/brake/etc., but it's more likely that the game handles acceleration while players focus on steering, gathering power-ups, and taking down foes.

There's a good precedent to look at here: Nintendo's "Super Mario Run." The game is still essentially a 2D Mario experience. You're running, jumping, punching question mark blocks and stomping on Goombas. But instead of having to careful maneuver Mario left and right, the game automatically handles Mario's running. It's not a perfect facsimile of traditional Mario, but it's pretty close.

"Mario Kart Tour" was first revealed during an investor presentation by Nintendo president Tatsumi Kimishima.

Here's the full announcement:

"We plan to release a smart-device application from the 'Mario Kart' franchise, 'Mario Kart Tour,' during the next financial year (from April 2018 to March 2019). We will announce further details at a later date."

Not that thrilling, I know.

Nintendo's American Twitter account had a slightly more exciting take:

"The checkered flag has been raised and the finish line is near. A new mobile application is now in development: Mario Kart Tour! #MarioKartTour Releasing in the fiscal year ending in March 2019."

There was an image of a logo included, and that's it.

We asked a Nintendo representative a variety of questions regarding "Mario Kart Tour." What kind of game is it? Who's making the game? Is it free-to-play, will you pay up front, or some other model? When will we learn more? Unfortunately, we were told that Nintendo doesn't have anything more to share at the moment beyond what was put on social media.

Given Nintendo's approach thus far to smartphone gaming, it's just as likely that "Mario Kart Tour" is free (with paid elements) as it is that it costs a lump sum outright.

That said, "Super Mario Run" is a good place to start thinking about "Mario Kart Tour" — both are core Nintendo franchises. "Mario Kart 8 Deluxe" is the second-highest selling Switch game to date, behind only "Super Mario Odyssey." It seems entirely likely that "Mario Kart Tour" offers a few levels for free, then charges a lump sum for access to the full game (like "Super Mario Run" did). It's the kind of game Nintendo can demand a premium for, and likely will do so as a result.

Will "Mario Kart Tour" be profitable on its own? Who knows! We don't even know if it's going to cost anything.

What we do know is there's a behemoth "Mario Kart" game on the Nintendo Switch console that's already sold 7.3 million copies. It costs $60, and the Switch costs $300. If Nintendo makes money on "Mario Kart Tour" matters of course, but it matters much more that some of its players are convinced to go buy a Switch console and/or a copy of "Mario Kart 8 Deluxe."

In this respect, it's likely that "Mario Kart Tour" falls into the third category of Nintendo's so-called "main goals" for its smartphone business: "Synergy with Dedicated Video Game System Business." (It also serves the first of those three categories as well by default.)
