www.simsforums.com - the Sims series, computer games & other nonsense since March 2008.

The second aspect of The Sims 3 that always impresses me is our completely reinvented and realistic Create a Sim. In The Sims 3, you have so much freedom to create the Sims that you want to make, yet it’s easy and fun. In the coming weeks, we will have some screenshots on our website that show you a small glimpse of what is possible with Create a Sim. The Sims can look like anyone you imagine. I’ve made my friends, my great grandpa, and many other important people from my life. We also have a new realistic personality system called Traits that allows you to determine the personality of every Sim. There are dozens of Traits that you can assign to your Sims. Every Trait will change the way that your Sims feel, think and behave in the game. You can choose several traits for your Sims, so it’s really possible to make any character that you can imagine and they will come to life in The Sims 3. Now imagine placing these unique personalities into your very own “Petri-dish” that is the new seamless, living neighborhood.
