Is the Sims 3 like the original Sims computer game?

I am interested in buying the Sims 3 game. Is the game like the other Sims games on xbox where you have a story line to follow? Or is it more like the original Sims computer game where you can build your house add accessories and you have to make sure you eat, use the bathroom ect? I like that type of game better where it is like actual life. What are some of the things that you can do in the game? Can someone explain it to me. Thank you!Is the Sims 3 like the original Sims computer game?
Alot has changed since "The Sims" but the original concept is the same.

In the Sims 3 there isn't a storyline. You can make your own, or not, it's up to you.Is the Sims 3 like the original Sims computer game?
nope.
