Well... you said "most" and I think anyone would argue with that. If you had said "all" we would have to argue. A lot.
There are games, even from the Atari era, that hold up well, but just if people trying them make the effort to clean their mind and understand the era when that game was launched.
It´s like watching an old movie.Movies like Limelight, Metropolis and Nosferatu are quaint compared to today´s movies, but if you understand the industry standards at the time they were launched, and how people used to appreciate movies back then, they can be quite enjoyable.
Games like Keystone Kappers on the Atari, Sonic on Genesis/MegaDrive, TMNT 3 and SMB3 on NES etc. have great gameplay and are quite enjoyable. We just need to be open-minded.
