Do you still have hope?

I can't see them doing an overhaul of the emotions system when they can't fix smaller issues like persistent bugs.
I want to be hopeful, but the track record for the series at this point in terms of fixes gives me no reason to be.

i do not think anything needs to be fix the game is perfect as it is

New traits are being added all the time with various new packs which should have added impact on the emotions being shown but it all seems a bit "loose" at the moment. It looks like the basic emotional aspects from the base game are lagging behind and need to be worked on to catch up. It's as if they are unfinished, waiting for future developments.

There are some really nice emotional interactions in Cats and Dogs which affect mood for example. I'm finding it getting better after all packs added and the game has more depth than I thought. It's rather like we'll probably get more "death" emotional reactions if they supply us with a cemetary and mausoleum in the future but they should have been there from the beginning.

I don't think they'll fix the core gameplay its been 5 years. I hope I'm wrong but I feel if they were going to bring us unique and smarter sims they would have done it by now.

I’ve been wanting freed babies forever, for example. Still haven’t gotten any updated babies, so I doubt most other core stuff would be updated.

Now I wouldn't go as far as saying that nothing at all needs to be fixed, but this comes closest to how I feel about this issue.

Musical Chairs and the constant sitting down during conversations, for example, are/were a big problem for me. At them moment I have a mod to deal with it, but the next big patch is already around the corner, so we all know what will happen to it :'(
But I always was and am still fine with the core, because several of the big problems just do not come up in my game. I'm too much of a micromanager to wish for independent sims personalities or moveable babies. Even simulation lag takes a long time to rear its ugly head in a no-autonomy game.

It's a perpetually, self-winding mechanism of disappointment.

No, if it hasn't dawned on them by now (TS4 is Five in two months) after all the threads about it then there isn't any hope at all. Why would they do that when in a few weeks they will be ending support for the low end machines and they won't be able to get any new packs and possibly they won't be able to get patches, or new content, either.

I mean how can they patch a 32bit game with things that will be affecting new packs in bug patches etc.? How are they going to separate all that? So, no, they have no intentions of changing the core of the Sim at this late in the game's life span. Five years of ignoring the major complaints of this game proves they have never even thought about it or possibly don't even understand the backlash at all.

There are some bugs that I think can and will be fixed, even if it takes longer than some are willing to wait. But I think the mechanics of the game itself are just fine as is - that's just me personally, I know a lot of people think the game is awful and tbh I am not sure why they still play in that case. I love this game!

Of course, I'd love for there to be more in-depth personalities, zodiac compatibility, and a wider variety of emotions... but the lack of those things never weigh on my mind while I play. The only thing I ever got frustrated over not having in my game was the pool tool. But they added that, and I've lived on and played happily ever since. I love the addition of new free content, and paid content as well (though I wish it wasn't so expensive).

Overall, I don't think the game needs "fixing."

I agree with @storyy .
