There was a Sims Online game, but it was based off of the Sims 1 engine and not many people played it.
Sims 2 is great, though.
I forget which expansion gives this home item, but its this flame jet thing on the floor, and every so often it'll burst out a flame and light, and looks awesome. FYI, you can catch fire from it. Put a fence around it unless you want a gay firefighter to come, try and flirt with the household male (If there is one) and drive off the road and into the forest (If you live on a corner).
