Thinking about Getting Famous...

They do fawn over celebrities but not in a terribly bad way. Also, not everybody fawns. However you do not want a popular venue like a cafe or bar to be a celebrity hotspot, cause they will be swarming with paparazzi and other sims will only fawn and take pictures and faint. You can disable gaining fame by default but you can work on it if you want to advance for one particular sim, so it's not completely disabled. The world is pretty and there are some nice events, like singer celebrity sims spawn around town and sing and other sims listen, once a celebrity sim in my game fell asleep on a bench in the park and the fans gathered around him and chatted instead of taking pictures and stuff. There's some nice build and buy items and clothing from the movie sets, I particularly love the pirate ship. I have a sim who collects autographs from celebrity sims. There's more ways to play with fame, not just the actor career.
