Yeah, I killed the Newbie family.
That game really let my architectural and landscaping creativity out wild. Before playing the game, I never knew I had the ability to design good houses, and that really impacted my life. Now and then, I still sketch "blueprints" of the estates I want to construct. This may be my great-grandfather's genes talking, but hey, praise the Sims!
Oh, I also credit that game with giving me my first memory of drowning a person... I just wanted a blue ghost, don't give me those funny looks.
