I am 48, and still play it from time to time. But not for the same reason as most of you, unfortunately.
3 days before Christmas 1991, I was 33, and never played a computer game before.
I was at the time in Germany, and just dropped my little girl and my wife at a local airport for meeting her parents at Heidelberg. I was due to join them by road on Christmas day as I had to finish a job before.
When I went back home, it was empty, and I was feeling just too lonely. I went to a friend's home and found him very excited as he had just received Civilization.
We shared the evening trying to undertstand how this game was working, totally unused to video games and amazed by the complexity of what was for us something incredibly "big" and unexpected (we were still with a mind: game = pacman or rubik cube ...)
At the same time that I was having a great time with my friend, and probably in the middle of one of our "strategical" discussions, the Douglas DC3 that was carrying my little family crashed. They were killed with 26 other people and crew.
This made a turn in my life, and from this year, I moved on to a different job, bringing me into many different countries where some sort of assistance is needed. When I left Europe in early 1992, in my bagage I had the civilization 1 that my friend offered to me, just telling me "you had a good time with it, it will help you having more good time and forget a bit...".
Since then, I play this game, from time to time, as it has not for me the same savor as for all of you (I hope), and simply brings me back in time, like an old friend, softly.
It was long ago now ...
