Sims will now age.
Sims will have 6 different stages in life: Infant, toddler, child, teenager, adult, elder and then death.
Sims will now be able to pick a shirt and pants, instead of picking an already made outfit.
You will be able to take accessories (Hats, jewelry etc.) off.
A retired elder will get a pension every month.
Our Sims will now have to plan for funerals and weddings (Yes, I said weddings!).
When a female Sim becomes pregnant her belly will grow over a period of time.
A pregnancy will last about three Sim days.
When a pregnant Sim is ready to have her baby, she will be rushed to the hospital in an ambulance, and return a few days later with a baby (Or twins, or triplets!).
Teenage Sims will NOT be able to "play" or get pregnant, although they'll be able to have boyfriends and girlfriends.
Sims will recognize their relatives (No more brother-sister incest!)
We'll be able to put doors and windows on diagonal walls!
Babies and adult females will puke. Babies, just because that's what babies do, and the adult females will puke when they are pregnant.
There will be 4 stories total in a house.
There will be a community lot where you can go get ingredients for special meals.
Teenagers can run away, and their parents can either do something to get him/her back, or not do anything at all.
Teens and elders will have 7 careers to choose from, and each career will have 3 promotions.
You'll have a choice to send your kids (and teens) to a public or private school.
We'll now be able to build on non-flat land!
Objects will now age, and the cheaper the object, the faster it'll age.
When an elder dies, the child that had the best relationship with him or her will get the most inheritance.
Sims will have facial expressions.
The camera mode will be amazing. We will be able to place the camera under a Sim as they jump into the pool, hide it behind a potted plant while two Sims make out!
