It's the old "back in my day" mentality. There were plenty of terribly shitty platformers for the SNES, but they are easily forgotten, leaving us to recall the good titles. The same goes for every generation of gaming. There are lots of great new games, but for every great game, there are at least 5 mediocre titles, if not more. Same goes for music, movies, etc.

There isn't a single generation of games/music/movies/literature which doesn't have memorable works. The same will follow for the current gen.
