Sims is both for the computer and gaming systems. You can buy it Best Buy, Circuit City, GameStop, etc.
In the game you can create people and run their lives (getting them a job, creating friendships/relationships, building and furnishing houses).
The website(
www.thesims.com) has more detailed information and actually shows you shots from the game. I prefer playing on the computer, I bought it for my Xbox and didn't enjoy it at all.
