I first really started to learn how to use computers playing Leisure Suit Larry on a friend's dad's computer. Started with copying save-games to/from floppy disks, to using MS-DOS in general, to BASIC, etc. and so forth.

It's interesting how much of the humor in those games flew way over my head yet I still had a blast playing them. And looking back as an adult, the "risque" stuff was tame as hell but still fun. Sigh, good times.
