I LOVE a lot of these ideas.
This is hard lol.
Some worlds I just want to see, but I did not have some specific theme for them I guess. And there's themes I'd like for packs that don't necessarily fit with any of these worlds (and, well, some packs don't really need new worlds).
I gave it a try, though, but doing it the other way around (some I have thought of more than other, so I just tried making them fit in a world):
Romance EP: Greek Islands
- more relationship types and unrequited love
- preferences and chemistry
- ability to fake being in love
- slowdancing
- cuddling in bed
- bicker about...
- kids reacting to walking in on their parents during woohoo or a fight
- npcs reacting to public proposals
- an option for sims to stop a wedding during the ceremony
- best man speeches that could either be well received or embarrassing depending on traits
- meet the parents (nothing fancy, like hang out or welcome wagon)
- breakfast in bed
- chocolate-covered strawberries
- bachelor/ette parties
- honeymoons
- anniversaries (with a surprise free dessert maybe depending on pda level?)
- share dessert
- double dates
- a dating app
- a specific area of the world where the interaction to watch sunset appears in the afternoon
- maybe a world-specific option to take a stroll holding hands
Music GP: Korean City
- concert venues
- drum sets
- electric guitars
- bass guitars
- ability to form bands and rehearse
- ability to play gigs at bars
- vocal harmonies
- choreographies (group and solo)
- world tours
- shooting music videos
- ability to form an entourage (so you can travel with your manager and assistant or something)
- playable album launch parties
Resorts EP: Brazilian Beach Town
- run a hotel
- check into a hotel
- have a second property and rent it for the holidays as an extra income (with possible negative consequences)
- get pissed off at tourists
- have demanding guests make a scene
- celebrities with bad reputations can trash hotel rooms
Medieval GP: Scottish Highlands
- dragons
- royalty
- piracy
- swordfighting skill
- archery skill
- blacksmithing skill
- having to empty the pot chamber
- a working well
Happy Haunts GP: Spanish City
- that ghost hunter career they mentioned
- a ouija board
Outdoor Activities GP: Swiss Mountain Town / South African City
either
- surf
- paragliding
- kayaking
- spotting sharks in the water
- mountain biking
- atvs
or
- hot springs
- snowboarding
- snowmobiles
- sledding
- igloos
both
- a peak they can hike to where the option to take celebratory selfie at the top appears (maybe they can teleport via cable car there too)
- go pro cameras
- ferris wheel
- a new aspiration
- adrenaline junkie trait
- actual wildlife encounters (not sims in bear costumes, although that's funny)
- new deaths
Farming EP: Chinese Countryside / Italian Vineyards
- I only know the very basics of this
Not-Sure-Of-The-Theme GP: Spanish City
- everything they said about heists!!!
- a hand-to-hand combat skill to build on the sparring from the military career
- a help others / do good in the world aspiration (that can work with several existing careers like doctor, politician, environmentalist, etc, and benefit from charity and volunteering)
I'm not sure what to use the rainforest for, but I sure would love some tree houses. Maybe more occults like werewolves, fairies and elves?
And there's other GPs I'd like that would either need a world not listed (like something in outer space where they can leverage that partnership and like give us light saber fights; or an underwater world) or no world at all, really. There's just a lot of features they mentioned that I'd like to have all together in one EP focused on family play:
- active schools (IF they were to add cheerleading, I'd prefer it to be in this context)
- family outings/gatherings
- strollers
- funerals
- that healthy living aspiration (complete with the fitness watch)
- pool parties
- slumber parties
- that portable telescope they mentioned
- shopping malls
- ballet
And some features should just be patched in, like prosthetics, spiral staircases, the ability to check the weather, c o n s e q u e n c e s, multitasking for lounge chairs so sims can talk and have a drink, etc.
