With the latest of the Sims game franchise... I bet you can! Sims 3 is schedule to hit the market in June but I'm not sure when it's going to come here in Asia. Can't freakin wait. I know it's going to be super, based on what I saw and read in the magazines and on several websites.
According to wiki, and I quote, "Personality configuration for Sims has also been made more complex, with the original 'percentage bar'-style personality points replaced by a combination of traits, similar to those in the personals section of newspapers. Toddlers have two traits, and a new one is added for each new life stage, until they reach young adulthood—so they will have 3 as a child, 4 as a teen, then 5 as a young adult, which are the five traits they will stay with for the rest of their lives. When creating a Sim, however, all trait spots do not need to be filled.
Create-A-Sim now features more than 60 unique traits to choose from. It is not possible to give a Sim traits that contradict each other (such as Brave and Cowardly). The player can also edit a Sim's favorite color, music genre, and food."
Only one word that comes to my mind...Awesome!
