I LOVED the Infocom text games... Zork, Wishbringer, Planetfall, Leather Goddesses...
Occasionally I'll find a ported game on the web and play for awhile.
My first experience with Zork was on a PDP machine at my college in 1983. After I graduated and got my first PC I bought a couple of the games that had been released for the various IBM clones and then friends and I traded them back and forth.
