What is your favourite way to play The Sims 4?

Builder and player

CAS, building and playing, depending on my mood. Spend more time building and playing, though.

I play my sims after I build their worlds with their timelines. I play from Prehistoric, Medieval, 20th Century to Futuristic. I actually have 4 complete Game Saves in my Sims 4.

I spend the most of the time playing, but I also like making Sims in CAS.

I primarily play, but that's after I spend time creating my Sim(s) in CAS. Then, unless I already have a build for this Sim/family, I'll spend time creating just the right home for them. Sometimes, I'll take a break from playing to create another new lot for the Sims I'm currently playing. I find building relaxing, for some odd reason. It's a great way for me to unwind, anyway. I've been turning to it more and more, lately …

I spend about 80% on actual gameplay, 15% redesigning lots I've downloaded, and about 5% in CAS. I usually only go into CAS to change my one family's outfits or after the release of a new pack. Lately though I've been thinking about creating a bunch of sims and adding them to Not In World to hopefully get rid of some of the game generated townies.

Playing with my sims. It’s all I want to do in the game.

Majority playing, but when I lose interest in the household I'm playing I spend all my time making sims or "fixing" the world with better houses. I don't build many of my own builds from scratch but pretty regularly I'll be looking to replace lots with better ones from the gallery.

I love to play the game and create families/legacies even with the NPCs. I also edit the Townies and their last names so they won't have the same last name unless they are related. I know people can share the same last name and not be related but it's how I identifty certain families.
I do spend some time in CAS when my sim changes their style or ages up. And I love sims to dress uniquely or at least not the same outfit as others. I don't build but I furnish if I get tired of the way a house lools since I play with legacy families. With all that being said, I am a solely gameplayer/storyteller.

I primarily build CC-free Sim-versions of characters from other games and sometimes film. Made my own Kylo when the Star Wars pack came out and EA's looked goofy. Currently working on Apex Legends and Cyberpunk 2077 characters. Crypto's done, still working on Wraith, Human!Revenant and Servo!Pathfinder. Today I'm just finishing up Evelyn Parker, Hanako Arasaka, Yorinobu Arasaka, Saburo Arasaka, Goro Takemura, and Sandayu Oda from Cyberpunk, then gonna try my hand at female V, Johnny Silverhand, and maybe Judy, though I'm not sure her immaculate beauty can be translated into the sims without mods, and I'm on console. I've got part of Clouds (the Dollhouse where Evelyn works) built, then I plan on building Lizzie's, The Afterlife, V's apartment, and continuing to turn San Myshuno into (a pathetic, CC-less attempt at) Night City.

I've just recently gotten into building this year during lockdown. I'm not very good yet, but I like to think I'm pretty creative. I've got a four-story spooky victorian gothic mansion and a magical pink-and-gold she-witch house, plus a modern witch school on the gallery, along with some reno's of pre-built homes. Just finished an enormous Japanese family compound and threw it on there but IDK, it's messy and not my best work.

Anyway by the time I'm done building every character and making their houses, I'm worn out and barely play with them before I get sidetracked building new sims, who then need homes, and the cycle continues, lol.
