I feel the same. If a game has genuinely poor design, ugly visuals and atrocious framerate, it's always been that way. Games don't get worse over time, all that changes is one's willingness to appreciate the context of a game's development. I mean, that applies to all forms of media. Watching any old film, tv show, reading old books or examining old paintings, it is all done with a mind for it's era and the cultural and technical circumstances that influenced it's creation and it's own influence on future works.
I know I spent some time with some godawful games as a kid because I certianly couldn't afford to be picky, but those games are mostly completely forgotten by now. Most of the PSX games people remember these days, like Silent Hill, MGS, Biohazard/RE, FF, Chrono Cross, Vagrant Story...they remember them because they were are genuinely fantastic games. They will be fantastic forever and their influence will never diminish. If anyone has trouble appreciating or finding any enjoyment from them, they probably never really liked them to begin with, or they simply lost their connection with the era that produced them. A truly awful game would not withstand the baptism of time and linger in people's minds.
