Nintendo Land is not Wii Sports, but it occupies a similar territory in the lineup of its new console: it's a pack-in (with one particular bundle), it's a minigame collection, its games are designed to teach players how to use Nintendo's latest weird controller, and, most importantly, it acts as a statement of intent for the console as a whole.
For Wii Sports, that meant simple games, based on familiar real-world sports and built around real-world movements, all designed to be comprehensible and fun to people who had never played a video game before, and, it would turn out, would probably never play another.
But the Wii was a console designed to be less complicated than any previous, whereas the Wii U is in fact more complicated. Nintendo Land, accordingly, expects a deeper video game background and a more complex skillset from its players. Wii Sports wouldn't be caught dead with dual-analog shooter controls, for example. Nintendo Land demands a more literate audience.
That's not a condemnation. It may not be for every single person on the face of the Earth like Wii Sports was, but if you can find four other people who know what Pikmin are or will recognize the two cops from Animal Crossing, you will have ridiculous fun.
