the traits seem like fun
Why not visit the local neighbor, or maybe play a prank on them.
Sims can now creep around the neighbourhood spying on other people
thats what ive been wanting to do in the sims in like forever
You can create morbidly obese Sims! New 'weight' and 'muscle' sliders allow for some truly impressive - or disgusting - creations
finally even tho a few people have already added the meshes to the sims 2 but in the sims 3 its official

Sims think for them self, no need to wake up, go to fridge and go to word. The player does not need to focus so much attention on Sims any more.
this could be either a good or a bad thing
