Like/dislike overhaul suggestions.

While the idea of it is great, it bothers me that the execution leaves a lot to be desired and has never been fixed either. I feel like it is a feature that would be better to just go back to the drawing board with and revamp completely to release in an update. Especially since the plan is to stick with Sims 4. Make it the best Sims game it can be. 

First of all, less is more. Colours and decor styles can be ditched, it is not something that can really affect gameplay. I feel like it are things you can easily show in what you have sims wear and how you decorate their house or personal room. 

I would update it to have 4 categories that do each work in their own way: Food, music, activities and attraction. 

Starting with food, you can pick one favourite meal for sims, though a Foodie can pick three. eating this dish could make them extra happy and will also improve their relation with whoever prepared the meal. You can also pick disliked foods, sims will not like eating this and unless they have the good trait or such, they will like the sim who prepared that meal less for putting it on the table. Vegetarian sims will automatically dislike all meals with meat in it. Glutton sims can't pick favourites or select any disliked meals, they will eat anything. Anything not their favourite or disliked will just give the normal reaction. So if you like you can make a sim a super picky eater. If they have the grilled cheese aspiration, that would be their favourite and they'd dislike all other meals. 

For Music, I would let a Sim pick up to three favourite styles. When they play an instrument, they will play one of these styles if possible, when they turn on the radio by themselves it will be to one of these styles. Hearing it will make them extra happy, it can give them the want to dance. Some traits like dance machine and music lover can pick more than three favourite styles. You can also select all the styles a sim dislikes, again you can make them super picky if you'd want to. All music they dislike, they will never dance to, they will also want to turn it off, turn it to different music or move to another room depending on their traits. A hot headed sim while angry could even sabotage the stereo on their own. No need for sims to select music they just like, they are sims. By default they like everything. 

For Activities, I would expand it to more things. Like each expansion and gamepack could have something from it. Activities would not be limited, they can have as many favourites and disliked activities as they want, though traits can make them dislike some activities automatically, and some crucial to a trait could be automatic favourites. Like dancing for dance machines. Favourite activities Sims will try to do more often than by default, and disliked activities they will never do on their own, and will dislike partaking in if you make them. Other sims inviting them to do their favourite activity will boost their relationships a bit, while being invited to join in a disliked activity will make them like that sim less unless their relationship is high enough though traits will play a factor here too. Mean and evil sims would like any sim less for asking no matter how close the relationship. 

And lastly, attraction. All about what they seek for in a romantic partner. Likes and dislikes, which all adds up so enough likes will cancel out dislikes. They cannot perform any romantic actions with any sim that has more dislikes than likes, and will reject their advances too. If the attraction is -10 or lower, they could act repulsed by the other sim though traits could play a part in lowering or increasing that number. You could only pick physical attraction things in this category, anything that can be liked can also be disliked, or you just select nothing if it doesn't matter to the sim. Again, you could make them super picky if you'd want to. But could also make them seem kind of needy by liking everything. When a sim has +10 or more attraction towards another sim, they view them as irresistably attractive. Again, traits might lower or increase that number. How sims behave around someone they find irresisttably attractive could depend on their traits. Could see them as out of their league, someone they want to show off to, desperate to gain their favour, want to impress, too shy to talk to without stuttering, etc. 

The stuff you can select for physical attraction that can be liked or disliked would not be anything controversial, that would not be in line with the sims. Skin colours and hair colours would not be a thing for it. But being muscular or not, thin or fat can all be turn offs or turn offs to a sim. Other things would be make up, tattoos, a specific hair length since CAS does have that categorised, hats, facial hair, body hair,  jewellery, glasses, shades, specific outfit categories and also each super natural life state in your installed packs. 

Traits could allow you to see other stuff your sim likes or dislikes based on that in this panel too, but you can't change this and this would all be completely different things outside of physical attraction. All of them do count for more than one positive or negative point however, it weighs heavier. Not all traits add anything here though. But good and evil sims for example would have like a -10 modifier towards any sim with the opposing trait in terms of attraction. So if a good and evil sim ever date, it really is a big deal. Traits can also make other stuff than specific opposing traits as a dislike or their own trait as a like. Materialistic sims would obviously consider someone's wealth too, being less likely to date someone poor. A foodie sim would see a glutton as a reasonable negative, like -3 or so. It is someone who will never be properly appreciative of a good meal like them. The glutton could not feel the same about the foodie though, they could however see a sim with a high cooking skill or having a barbeque at their house as a positive. A sim who hates children would see another sim being a parent or family oriented as a negative. A family oriented sim might dislike a sim who hates children even more though. 

Again, anything you can pick is only romantic physical attraction so would not affect friendships. That only affects possible romantic interest. Sexual preferences would still apply too, like if a woman is only into women and not open to experiment, she would never be romantically interested in a man. If she is open to experiment someone who is not of the prefered gender could add a -3 modifier or such for attractiveness. 

The stuff from traits would not exclusively affect romantic physical attraction since clearly good and evil sims will hate each other no matter what. It would simply take that into account and show the modifiers in effect.
