In my teens, I used to play the original 80's Football Manager [0] on my BBC Micro for hours, in fact days on end....and I can't stand football :)

I know it's not the same game, and was never as sophisticated as modern FM, but damn it was addictive, even for a non-footy fan. I might have to take a look at modern era FM.
