There was some sentimental fun to be had, but these games take a tremendous amount of time to play and are difficult in a way that modern games are not. Their puzzles are almost unsolvable in some cases, or can only be solved by combining every permutation of every verb with every noun in every place to get the right answer.
Relative to what's available in the modern gaming realm as well as conventional fiction, I've also been pretty underwhelmed by what the Interactive Fiction community is putting out, especially the games that are purely web-based. There are some authors, Andrew Plotkin comes to mind, that have picked up the Infocom torch, but the feeling that you are using 0.1% of what your computer can do at about 5% of the rate your mind can work is difficult to shake for me in our modern era.
