Since everyone is interested in my potential Nancy Drew marathon, here's an update.
They do not have the Nancy Drew games at the library here in Portland, but they have them at the library back in California. I'm flying to California at the end of the month, so I can put a hold for them now and pick them up when I arrive.
Then, I'll install the games on my computer, so I can play them for the marathon. The new Nancy Drew game comes out in mid-May, so it's possible for me to do a marathon before the new game comes out.
Question: Is it possible to play the Nancy Drew games, without having the CD with you? I know you can do it with the more recent games, like Tomb of the Lost Queen, but I remember that some of the older games ran off of a CD. Ghost Dogs of Moon Lake did, at least.
