EA have launched a Sims 3 demo that will theoretically run in your browser. The demo was announced on the EA site, spotted over on Blue's News, and contains "elements from The Sims 3, The Sims 3 Late Night, The Sims 3 World Adventures."

EA's link doesn't seem to work, but we managed to launch the demo from the Gakai front page, the service providing the streaming tech behind the trial. The demo is time limited to 20 minutes. You'll be able to create a sim and lead them to their a gruesome death in an Egyptian pyramid, a haunted house and a vampire lair. Or you could keep them safe and watch them live long, happy fulfilled lives, but where's the fun in that?
