Shooting and passing depended so much on your body position, the skill of your player, the timing, the power bar. They were directly linked. Nowadays.... not so much. At all.
Everything else, besides shooting and passing, depended on all those factors I mentioned before. Player speed (much more noticeable before than now), dribbling skills and success at it, etc.
And don't even get me started on the AI. The AI was very good back in the day while still behaving somewhat humanly, making mistakes, failing passes, shots, ball control, even though they created many many more chances chances than they do now, they didn't always score. Nowadays, they're lucy if they get 2 shots on target by the end of the match, and half of the times, they score at least one of them.
