Modern games are generally going to be more approachable than old ones. Tastes have changed considerably. In the days when you couldn't pull up a walkthrough in a few seconds, taking days to think of the next step was part of the fun, and just getting permanently stuck at some point was fairly common. Also, letting the player keep going even after they have done something to make the game unwinnable is now considered very uncool. Navigation is much less tedious these days as well, fast travel for example, although the exact mechanics depend on the game.
And that's not mentioning the amount of CPU and RAM available, not only for the game's runtime, but also for tools like I7 (which was used to write Counterfeit Monkey).
