I like the idea of CAS stories but I don't like the implementation. If generating a background story is done only via quiz, then I think it will get old really fast. Why a quiz? I see it as being "fun" once or twice -- not every time I want to make a sim. And, honestly, my non-random sims are way more deserving of a CAS story then some random.
I hope I will be surprised by it though. Maybe we will have more options than what they shared? Always with the maybes....
EDIT: Just tried it out in-game. Here are my thoughts (and questions -- any answers would be appreciated):
So, the quiz reminds me more of a social app that gets shared on Facebook (or wherever). I don't think I'm going to enjoy doing that quiz every time I want to add a sim with a background.
Is there no way to add a story to ANY sim (not just new ones in CAS or added to existing families) without the quiz approach? There are more efficient ways to do so and they could be done by random or manual selection. So, while the quiz might be fun (once), a more effective method would give players much more choice without having to spend more time in CAS.
On a small positive, I like that they are still looking for new directions to go in, but I don't think a new direction is as important to the game in its current state than actually making the core of the game better.
Also, is there STILL no way to make one outfit in say, everyday, and copy it to another category in CAS? Because that is way more important to me than taking some quiz.
