Really sorry if this has been done before. I searched and didn't see exactly what I was looking for in the last year and I'm curious about your answers, so...here goes nothing!
How did your very first Sim die?
Was it your fault? What was your reaction?
Which Sims game was it?
For me, my first Sim died by fire in Sims 1. My sister and I were playing and we were young at the time and totally not expecting it. We panicked and didn't know what to do once the Sim caught fire, so we ended up turning the monitor on and off to try and stop it. Obviously that didn't work, so we unplugged the desktop in our hurry to save our Sim, haha. The Sim was fine after that but I think I was a bit traumatized, because I never played another family long enough (with aging on) to witness another Sim death until Sims 3.
