Things I miss:
* Witches - Of course, this is top of my list. D: lol. I want them to be so in-depth this time around! Really loved the Game Pack idea to truly focus on them.
* Sims University - being able to be apart of a Sorority/Frat, or Secret Society.
* Consequences - More death types, more challenge. (Burglars, more skills to allow you to start from 0 Simoleans and have to earn a living. Consequences for relationships, relationships being harder to obtain). I want a challenge, not easy mode. :(
* Interactions between children - Dance on mommy and dad's feet, cops and robbers, hopscotch, tag, miss Mary Mack, etc.
* Toddler table - drawing/coloring, blocks, etc.
* Babies - Being able to hold a baby and multitask. Being able to bathe your babies. Changing tables.
* Day Care Career - Would love to see this return in Sims 4. (Active Career).
* Real Festivals - I feel like Sims 3 had so many things for the festivals. I would have loved it if they added "stalls" to Seasons where you could play games, or if they brought back the kissing booth during Spring along with slow dancing... (The haunted house during "Spooky Day"), I feel like these were such a missed opportunity.
* Sleep Overs - I miss pillow fight interaction, being able to have sleep overs, we have Movie Hangout, I felt like this should have been included, along with "story telling", truth or dare, maybe Twister, (remember jumping on the bed, or sofas?)
* Being able to place lot sizes down.
* Different types of stairs. - (Spiral, L-Shape, Curved (Curved and L-Shaped are basically wants, not misses).
* Attraction System - I miss being able to select things that my Sim might be attracted to, or like/dislike. I miss reputation (not fame reputation, relationship reputation).
* Coward Trait + all the traits from Sims 3.
* The different types of deaths from Sims 3.
* Mermaids
* Island Paradise - one of my favorite expansion packs. I loved combing for seashells, scuba diving + skill, being able to collect all kinds of tropical fish, star fish, etc, etc and bringing them home and putting them in the aquariums. I miss the possibility of running into sharks, or dolphins, or gigantic squid monster that could take your boats down! That was so interesting. I also miss being able to run a resort.
* Photo-booth. I miss the pool table.
* Generations expansion pack - (Better weddings, all ages got some love in this pack and I loved it).
* Hobbies - Sims 2 Free Time expansion pack was a favorite.
* In-Game Story Album - Sims 2
* Peek-A-Boo interactions with toddlers. Nursery Rhyme. (Missed opportunity in Toddler Stuff).
* Private School - Headmaster would come by the house and make sure your house was a good layout (If your house was clean and well kept, etc.)
* Meteor Showers
* Fire-Fighters, Police, Burglars,
* Better Ghosts
* Ability to set the rotation of seasons
* The Ability to set the cycle of the moon
* Supernaturals - Sigh. :(
* Better Aliens - I love the disguises, but I feel like Aliens need a revamp.
* Small Pets, being able to go out into the world and collect all kinds of different animals (I miss owls, birds, and other little animals). Except snakes........
* I'll be honest, I do miss the color wheel. I miss CAST because I loved being able to take my favorite custom content, or favorite objects from packs and recolor them to patterns that I downloaded, or colors. I also miss being able to have different kinds of hair-colors because of the options we could have. I wish they would add a basic color wheel that Sims Players could configure and some talented Simmers could add onto it and add the options for applying patterns and such.. :( Because I understand that CAST was probably a bit laggy, but I do miss being able to apply patterns and colors to wall paper and floors because oh my goodness were there barely any options without it. Just like now... there's barely any floors and wall papers that I like that are in the game without CC. :(
* And I'll leave this list here. I am sure that I am missing a lot more! But I think this list is long enough.
Things I don't miss:
* CAS Sliders
* Toddlers not being able to walk upstairs, or crawl upstairs
* Not being able to plop houses down in the game through the gallery/ exchange
* Making sure to be out of the game in order to download houses for the game.
* Sims 3 Launcher
* Sims 3 Loading times
* Cost for traveling
* Cost for moving family to a different world
* Losing relationships when moving to a different world
* I am sure there are a lot more things I don't miss, but I'll stop here.
