Those Hallowed Classics

I was looking up an old LucasArts game, and although I haven't yet found any real webpages about it (leading me to believe that I may have it spelled incorrectly in my search string), I did come across this writeup in 1up.com's list of the Essential 50 Games. It's about a game called Myst that I played when I was in middle school.

Go ahead and have a look at the whole list. Any thoughts? I haven't played most of the games on there, but I've played a few, and they're all classics that seriously influenced electronic gaming. How about you folks? What are some of the games that you either loved as a kid, or think changed the genre?
