It enables you to make the players feel like "back in the days", but also to surprise them with state of the art concepts.
Games that are made like this create the feeling most people hope they get, when they play old games. They think about the times they had, play it again but often isn't as good as in the past, because over time they got used to much more stuff, which is missing in the old games.
Also - I remember that Nova Logic game (Commanche?).
