There are amazing retro games that are still awesome to play to this day. To say they all suck, and it's just nostalgia is not true at all.

Sure, a lot of them suck, especially on Nintendo 64, because of the 3d transition, but from the NES onward there are timeless classics.

My kid beat super Metroid several times, he decided to play it on his own on his switch, and he loved it. He plays the old pokemon games too. In other words, that's a terrible analogy.
