You're right, I forgot about the fact that it was "bundled" with an additional game. Personally, I only found out about this after I bought it; I'm not sure how much the bundling helped Mario Kart's game sales. But it's a fair point.

I didn't want to pick Nintendo Land because the way it was sold is not entirely straightforward. For example, some copies were bundled with a controller.

I didn't want to use NSMB or 3D World as examples because Mario platformers are often outliers when it comes to sales. I guess The Wind Waker HD would have been a good example, because it sold really well despite being an HD remake of an older game.
