At EA's E3 2011 press conference, CEO John Riccitiello was excited to announce The Sims Social, which is ... The Sims on Facebook. That's basically it. You'll be able to "play" a lower-res version of The Sims on Facebook.
There wasn't much talk in the way of features, but the announcement trailer was pretty hilarious and ultra creepy. We'll try to track that down for you guys so you can share in our misery right now.
