Electronic Arts announced this morning that The Sims will turn five years old this week. I remember people talking about this with some anticipation back in the late '90s, and it's already been half a decade since release. I'm not sure anyone thought it would be as popular as it has been however. The base Sims package has sold more than 16 million units, with its seven expansion packs adding an additional 38 million sales. The Sims 2 is on track to hit 5 million copies sold soon. Its first expansion pack is due in three weeks.
