The followup to Maxis's addictive-as-crack computer game The Sims. Apparently the marketing suits sat themselves in a room together and thought, "how can we make this even more life-killingly addictive?" Someone clearly saw EverQuest and mated the two.
Presently it's only available as part of a free beta test, and I've signed a non-disclosure agreement so I can't say much about it. Suffice to say that the gameplay is much like the original, but all the other Sims are real and you have full control of how you make your money. You can run a brothel, a casino, be a writer .. all the while letting your real life go down the tubes.
The Sims Online will eventually require a monthly credit card payment to play.
