When it comes down to it, the new courses are excellent. Remade versions of existing Mario Kart courses are fun, too, and take advantage of shifting tracks and routes. Each lap is often different, carrying one surprise after another. This expansion doesn't do much else when it comes to the mechanics of 8D. Once again, the CPU is lacking. It's abundantly clear that it can't keep up at higher speeds and so relies on barrages of items. There are better ways of making a player feel like they have to battle to get through a race, but they're not to be found in Mario Kart.
