I remember playing civ 2 in london, I left the sink running to do the washing up, it was a big sink, and would take a minute or two, so I nipped back into the bedroom to finish my turn....20 minutes later I realised that the sink was still running! I'd flooded the kitchen and Hall, we were a second floor flat and I'd managed flood the kitchen in the flat downstairs too. If the splashing noises from the kitchen had'ent gotten so loud I could have left it run for hours.
I claimed that a water pipe had burst under the sink when my girlfriend returned from work. It was that or tell her the shameful truth.
That was the last time I played, 5 years ago, but they say an alchoholic is never really cured....
