Sims 4 Packs (hunches & hopefuls)

EXPANSION PACK IDEAS
Family Living (this will bring back the toddlers and allow gamers to focus on more family-oriented simming. It would also introduce a more family-based neighborhood.)
Downtown Life (this would be a commercialized neighborhood pack that allows creation and access to places like stores, restaurants, clubs, bars, galleries, etc.)
Sun, Surf & Sand (a beach-themed neighborhood pack that focuses on tropical holidays and lifestyles.)
Snowbound (a winter-themed neighborhood pack that focuses on much colder climate holidays and lifestyles.)
Travelling Tourists (the Sims 4 version of World Adventures)
Fun & Games (this would come with a neighborhood that features a customizable amusement park and a selection of sporting venues)
Careers (the Sims 4 version of Ambitions)
On The Road Again (this would bring in a trailer-trash style neighborhood where it's riddled with mobile homes and camping trailers. It'd also bring back cars and hopefully big rigs where there'd be a huge truck stop-themed collection of objects and building items to work with.)
Animal Kingdom (this would bring back the pets, plus a jungle-themed neighborhood that's filled with a wilder selection of animals to work with.)
Spaced Out (a futuristic theme with new neighborhoods to choose from and alien-related content.)
Frats! (the Sims 4 version of University where the neighborhood is focused on a giant school and a collection of dorms, frat houses and hangouts.)
Crazy Cruise (this would be a neighborhood based on a cruise ship that would island-hop to a collection of destinations loaded with locals and tourists.)

STUFF PACK IDEAS
Going Goth (this would be all gothic-related items)
Vintage (this would focus on random items going as far back as the Victorian era)
Planes, Trains & Automobiles (ranging from kid's toys to workable vehicles)
Klondike (this would all be the kind of items you'd see in the wild, wild west and the gold-panning eras)
Rock It (this would be focused on music-oriented attire and items)
What's The Occasion? (this would be holiday-themed items that would cover everything from January's New Year's to December's Christmas and all the holidays in between)

I think you missed the most important one: SEASONS! (or at least weather!) I already miss the snow outside of my Sims house! Or rain/storms (I hope they finally add real storms!)

You're right. Totally forgot about that one. As I was doing the list I was eyeballing how soon I had to go to work. I did do the winter idea and the summer idea, but left out the weather. Oops....lol
