It's quite interesting to see how perception of game difficulty have changed. I find that most games that rely on precision movement and fixed difficulty levels are now easy to beat, and I guess parts of it is different controls (e.g. keyboard vs. a big joystick; I remember back in the day too how I was tremendously pleased when I got hold of a joystick that was so sensitive that I could hold it and tense up to make it shake to win on games that relied on moving left/right as fast as you could, compared to my otherwise preferred joystick, which was a heavy-duty Wico model because I had a tendency to break the switches on cheaper stuff), and part of it simply a couple of decades extra experience with computers.

Games that rely on speeding up opponents, on the other hand, like International Karate / IK+, still become "impossible" fairly quickly.
