>Ocarina of Time ran at 20 FPS on N64, not in SOME demanding scenes, everywhere.
And I used to find a lot of old games immersive - but I can't play them nowdays.
Things don't exist in a vacuum and my experience is impacted by what other experiences I've had to compare it to. There's a threshold in graphics/voice acting/etc. that just makes the games I spent weeks on as a kid not interesting at all (even for the sake of nostalgia).
I used to work on 800x600 CRT monitor with 256 colors and today I get a headache when I have to work on a low pixel density cheap LCD.
