For the first time ever, players can share the fun with a friend in the co-op buddy mode or take on up to three friends in the Life Moments Game on the Nintendo Wii, upload and download content on XBLA and PSN, including furnishings, houses, and player creations or experience a full life simulation on a handheld with Nintendo DS.
Create Sims with unique personalities, fulfill their desires, and control their lives within a living neighbourhood that you can customise. Unlock all-new Karma Powers and unleash them on your Sims: help your Sim get lucky with the power of “love connector”, bless them with the power of “age defier” or "instant beauty" or curse them with an "instant enemy" or an “alien abduction.” Use these powers wisely, because they may have unexpected results! As you guide your Sims through life, you can complete challenges to unlock additional items, new buildings and landmarks.

- Poltergeist – Make ghosts appear to haunt Sims.
The trailer for the Sims 3 console was released on June 14th, 2010. It shows many of the original features of the Sims, such as cycling around town and changing Sims' appearance. It also shows the newly-added features, such as 'Karma Powers', such as when a female Sim is exposed outside a restaurant, leaving her totally nude with only the blur to cover her, presumably after doing something bad. It also shows that, unlike previous games, players are allowed to build more than one floor onto buildings. Another feature seems to be the ability to have children in the game, unlike its predecessors: (The Sims 2, The Sims 2: Pets, and The Sims 2 Castaway). Also on the Sims 3 for Wii, Sims can have WooHoo, and players can remove the blur, and it also shows features from The Sims 3 PC Expansion pack Ambitions, although we don't know if they will be in the game. The 2nd E3 trailer features the Kris Allen song, "Live Like We're Dying" and shows the possibility of the ageing system as the trailer shows Sims life memories of when they were younger as well as one point of the trailer showing the 6 life stages from The Sims 3 as well as an elderly man with the Grim Reaper. The ageing system was later confirmed by Sam Player in an interview with Gamespot.
