SimDay this week consists of just 2 items (so far): the news that Superstar has gone gold (You can read the press release at the official site right here, if you prefer that look). Besides that, there's a preview of Superstar at IGN:

"Every morning along with the newspaper, you'll get a new tabloid that shows who's hot and who's not. You can use the tabloid to keep track of the top ten stars in the Sims world and track your own progress up the ladder of fame. The tabloid will also report on the various goings on of Studio Town.

"As a regular non-famous Sim you can visit Studio Town via a convenient tram that runs between the residential neighborhoods and the new studio lots. Famous Sims will instead be picked up by fancy-schmancy limousines. On the surface it works a bit like the extra areas in Hot Date. A new population of Studio people is spawned with your install so no two versions of the game will offer exactly the same characters."

That are just two paragraphs of an interesting read. You should really read the whole thing, as they explain quite well how some things work in the new expansion, and what you can expect.

That's it for this week's SimDay... but as it's still early some more stuff might be added later (or not of course).
