Mario 3 is still a good game today, and I know some kids that weren’t anywhere near born when it came out that still loved it.
Nostalgia isn’t the only reason to enjoy old games and “the bad” shouldn’t be assumed to be there for purposes of false equivalency platitudes. Even just counting predatory monetization, the modern game industry is worse on average than it used to be and its desired profit margins and methods of profit are different and worse than before with a more focused exploitation model.
