I think people are generally either leaving behind video games and going on to better things, or else they think it would be more appropriate to play more "mature" games, or else they just discovered something they like better. A lot of the people I know DO like Mario, or at least remember playing those games. The other day after PE I cut across the gym to go to my next class and noticed the piano onstage. Arbitrarily(or perhaps because I am drawn to play pianos when I catch sight of one), I started playing the Mario themes, and this guy heard and made me play next time after class. Another guy stopped and listened, and then the Gym teacher came out and listened for a second too. Everyone loves the Underground theme, it seems. Then today, people were singing random songs at the end of PE in the locker room, and I started singing the pokerap, which I remember the beginning of. Most people played or watched that show, and everyone left in the room sang the original theme song(" I wanna be, the very best...").
People move on from video games sometimes. It's just a happy memory, unless they get into the Teen games. Most people I know who don't remember Nintendo or don't like it are the ones who didn't have video games when they were younger and recently got their first console that wasn't Nintendo, usually a PS2.
If your day is bad, a nice comment at night can change everything.
