Unlike previous console games, using cheats causes challenges and achievements (Xbox 360) or trophies (PS3) to be disabled.
Furthermore, The Sims 3 will detect if a saved game is cheating and prevent challenges and achievements/trophies from being completed.
This led to some users or websites to post warnings about using cheats in The Sims 3.
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).
When downloading the DLC and Updates, It will freeze at a random percentage, then eventually will show that the download is 100% complete and freeze. As of now, no one has found a solution to this glitch.
When your Sim dies, they will be playable as a ghost for five in-game days.
For the first time ever, players can upload and download content via Xbox Live and Play Station Network, including player creations from the Exchange for free and new items released by EA, which cost a fee.
