I made an evil, hot-headed, mean spirited,children-hating daredevil, and his childish, excitable, crazy,clumsy and slobby wife. . The first 10 minutes he called her mother a Llama three times, yelled at her, and she was talking to the mirror for a loong time
The cool thing about the traits are that you can't put opposing traits on the same sim. If they are grumpy, they can't be hot- heades, if they hate children, they can't be family oriented, etc..
I really had the intention to buy it... Until I actually downloaded, played and a couple of hours later uninstalled the game. I wouldn't trade my sims 2 with all its custom content and great hacks and everything for this... Apart from the traits system, there is nothing that seems to be superior to sims 2... Even most of the furniture is the same!
