Fortunately, the correct answer is in the lead now, but it's still sickening to me that so many so-called fans would think 64 was the first. I could understand if they were young and didn't care for the spinoffs, but still.
Taking out the poll, It looked like you were talking about Super Mario 64.
Imagine that.
Super Mario Bros. for the Nintendo Entertainment System even to this today is a fan favorite, a cult classic, a broad appeal, and an industry standard. It's also probably the most well known game ever (though Samus Aran would have something to say about it being the greatest). If you get people saying SM64 came first, they are also saying that
THEY DIDN'T KNOW SUPER MARIO BROS. EXISTED. (That's supposed to happen with the Zelda series. C'mon, guys...)
