here's my list, it's a long one:
build/buy:
sectional couches, preferably in a system like the counter and island pieces where you open up a menu with the separate pieces and combine them
BUNK BEDS!
dirt comes already placed under plants
easier split-leveling
stairs can be placed diagonally
curved walls and windows!
curved pools!
more wallpaper and floor options (for the floors, less wood and more tile and carpet, we have enough wood)
better bed proportions, the "twin bed" in the sims is almost HALF the size of what it is irl
throw pillows for placing on beds, couches and chairs, they're always so empty!
MATCHING WOOD TONES
matching frames for paintings!
changing light color in build mode
more realistic clutter options
CAS:
a color wheel would be GAME CHANGING
a "tween" age, right in between teen and child
a lower pitched voice option for children, they sound like chipmunks!
shorter teens
a height slider
a trait system just like the sims 3, that was SOOOO much better!
two parts to everyday wear: outside wear, inside wear (like, who wears high heels inside their house to watch tv?!?)
more categories in accessories: belts and jackets
more skin details: vitiligo, rosacea, acne, port wine stains and birth marks, other skin problems/genetics
a not-so-smooth skin option, how are they so smooth?
if no color wheel, we NEED more hair color and eye color options
nail polish
better eyelashes
Gameplay:
I'm not a huge gameplay kind of person, but some things I would like to see are:
more romantic interactions
relationships between townies
more tea going on with the townies maybe?
Packs:
farming/horses ep
cars gp (maybe you're thinking it should be a ep, but they already have made a lot of the animations and designs for debug non functional cars, yet still I don't know that much about making a game sooo)
snow activities gp (skiing, snowboarding, sledding, and maybe even houses on mountains?)
video games sp (arcades, playable video games, colorful and fun items)
amusement park ep! this would be sooooo fun
baby sp (baby showers, obviously better baby system, pregnancy shoots, cute items for nurseries, ACTUAL PREGNANCY CLOTHES, maybe teen pregnacies?)
the sims 4: get to school (take you child and teen to school, take tests, make friends with who you want, bullying, online dating
Misc/Worlds:
world creator? is that a crazy wish? they did it in the sims 2...
open world; at least in each world seperate (like in the san myshuno open neighbor hoods, but the whole world is open)
more hidden worlds, they're so cool, seriously
cool easter eggs! I love secret parts of gameplay
more icons that aren't irl, like cowplants and grim, so iconic! I want more crazy, weird, fun things like that
ok, finally, that's it folks
SIMS TEAM GET ON IT
just kidding :)
thanks for reading!
