Death and Destruction.

The husband of one of Catherine's co-workers heard I like to build stuff, so he sent her home with a copy of Sim City 3000. It's pretty good, but so far all I've really felt like doing is getting cities all established, then killing all the people off with tornadoes and fires and earthquakes. And aliens. But it keeps me occupied during my insomniac hours. I can lay in bed and plan out new cities, then it's a really quick thing to build them up to the killing off point the next day.
