There are loads of great games that come out all the time now, people just forget about bad games of the past.
And the "worst" games that we see now are at best mediocre if they were coming out 2 generations ago. The bar has gotten higher because so many high-quality games have been released
It's easy to forget about the bad games. I always think of the snes/n64 as some golden era where all games were great, but when I go to used game stores I remember that it's not true. There are a handful of great games from every era, and hundreds of forgettable ones.
