My first adventure game was KQ1... the original on a big floppy disk! My dad got a copy of it and my sisters and I stayed up until all hours of the night playing it on our big clunky IBM clone with a green monochrome monitor.
I didn't have my own computer until years later, then got KQ3 and DOTT and then eventually I just kept buying games when I could afford it (7th Guest, 11th Hour, Myst, more KQ, some graphical Zork, GK, etc.).
I took a few years off games but recently got back into them much to my husband's dismay.
