I think one of the biggest differences nowadays is that you play lots of players under 2100 in tournaments. Looking for example at the tournaments Colin McNab played 20 years ago, there were very few players of that level.

Bear in mind that the floor of the men's FIDE rating list only dropped below 2200 in 1992, so back in the day these players would nearly all have been unrated. (If I'm being pedantic, some "under 2100" players did exist - the floor of the women's list was 2000, and had been 1900 before every female player except Susan Polgar had their rating boosted by 100 points in 1984.)
