I used to kill sims to see the color of the ghost when I first started playing. At first, I didn't even know they could die. So then about every game I played I would kill off the sim, usually in water because I thought the blue ghost was cool. Also, I used to kill the sims because I like hearing the grim reaper music and seeing the ghost. I don't do that anymore now. In fact, now the ghosts kind of creep me out by the way they float. But if I get mad enough...yeah, you get the picture. But I usually don't kill sims unless I'm really mad at them, anoyed with them, or just want to add a little drama. Though I would like to see my first meteor strike and what the ghost looks like, I still don't try to kill them by meteor though, if my sims are going to be killed it is usually going to be by accident or old age.
Edit:ok, so maybe I HAVE been trying to get my sim killed by a meteor.
