Legend of Zelda franchise.
That is all!
Usually when it comes to Nintendo, the first 3 big names that come to mind are Mario, Pokemon, and Zelda.
But not even Zelda has managed to maintain the level of mainstream success that the other two have over the course of it's 29 year history.
All my coworkers, for example, know what Mario and Pokemon are, even those who've never played a video game in their lives, but only 2-3 of them have heard of Zelda.
And I just find it as a shame. Because personally while not their biggest or highest selling franchise, I do strongly believe that the Zelda franchise is Nintendo's very best in terms of quality.
This is the only one franchise I've encountered so far that I can honestly say to people I meet, "You HAVE to try this series just ONCE! It's THAT amazing!"
