I am so stoked!! This article seems really promising, and with this partnered with the video that was posted yesterday wants and fears are pretty much confirmed. That is awesome as I loved that feature in the sims 2 and it will hopefully add the slightest bit of challenge/personality to the gameplay as you avoid your sims' fears and have small-term goals with fulfilling wants. I'm really hoping the want/fear system is based on a number of variables such as your sims' traits, aspiration, likes/dislikes, lifestyles, etc.
I'm even more excited at the possibility of an attraction system and being able to customize your sims' sexual/romantic preferences. I also like the idea of my sims' partner being able to dump them, but I do hope that it has more to do with romance/relationship level rather than it being random like I've seen some others mention already. I think it would be a little too heartbreaking if I was too invested and my sim ended up getting dumped by who was supposed to be their soulmate, haha. I might need to go through all of the stages of grief myself to recover, lol. ?
