I've seen many people say (about games in general) that older games often have more depth in contrast of newer more "casualized" games that cater to the lowest common denominator as often as people say what you wrote. At the end is really about personal taste and if there is one objective thing that older games often do worse (apart from technical limitations, although with the popularity of retro-styled games nowadays often these limitations are seen through a stylistic prism) is their user interfaces. But even that divides people in how much they can endure it (and as Dwarf Fortress shows, a lot of people will endure the most obnoxious of UIs to get something they like).
As an example, there are many people who like grinding in JRPGs and some even consider it as a defining element of JRPGs (in that a JRPG is not real JRPG if it doesn't have grinding) whereas others are perplexed by the idea of anyone liking grinding and not seeing it as a cheap way to pad the game's length and something that developers should strive towards eliminating.
