Played adventure/colossal cave on a mainframe in about 1975. Never really got into D&D as already working, playing (Field) hockey at a sub-elite level, had first serious relationship at the same time.
Actually modded (changed code) of a colossal cave version in Fortran on a PDP-11/70s from 1979-81. Then when I got an apple II+ in 1980, I played Zork, Zork 2 in large chunks of time.
I never did much with a C64 or Trash80 but certainly spent chunks of time, mainly programming, ZX90 & ZX81.
Drifted away from gaming as was systems programmer on ICL29xx machine and had it for my own use on weekends, now that was a real personal computer! Joined IBM and was working too hard to do much gaming and didn't have a PC. I did a stint in the US with IBM 1989-91 (white plains, New York) and when I got back to Australia I was introduced to Civilization & SimCity and lost my nights for a while!
I was a beta tester for the original galactic civilizations on OS/2 (downloading that over a phone line was not ideal!). I then changed jobs at IBM and worked an average 65+ hour week plus travel (mainly international) 3 out of every 5 weeks - so no real gaming.
Left IBM but got unwell, very unwell, for several years so no gaming as the main issue was both wrists. Recovered, someone pointed me at BGI and that led to a gaming binge. Took a break for a few years while I did a part-time PhD and then played ME2 on a recommendation and been lost since then!!!
