If you already played "Mario Kart 8" on Nintendo's last console, the Wii U, you've already played the main section of "Mario Kart 8 Deluxe."

If, on the other hand, you're getting some serious déja vu from hearing about "Mario Kart 8 Deluxe," it's likely that you spent some time with the Wii U game. That feeling you have is spot-on — "Mario Kart 8 Deluxe" is very similar to the 2014 game for the Wii U. In fact, "Mario Kart 8 Deluxe" is the same game. The difference is in a handful of tweaks, and a new Battle Mode (we'll get to that in a minute).

Here's what isn't different about the "Deluxe" version of "Mario Kart 8": No new race tracks.

That might be huge to you. If you played "Mario Kart 8," and played the additional content Nintendo sold after the game came out, you shouldn't expect a bunch of new race tracks here. Nintendo's banking on you not having played the game on Wii U, and that's a pretty good bet considering how few Wii U consoles were sold.
