Oooh, this is really interesting!
If I were to describe my old gameplay style (dating back to TS2 days), I would say I was a goal-oriented simmer. I would either play young adult sims or families, and I always enjoyed completing aspirations, maxing out skills and reaching the top of career tracks. I never used to think of backstories for my sims, and I never got attached to them.
In 2018, my gameplay style evolved quite a bit. I still enjoy achieving goals in the sims, but I think my style has shifted from purely goal-oriented to a micromanaging storyteller. I still like to play either young adult sims or families, and for some reason they’re never occults. Just a preference of mine, I guess! I also play my game with aging off for active sims as I keep track of my sim’s birthdays, or age-up days rather. Any unplayed sims don’t age at all unless I manually age them up, so I should add I don’t play my game completely realistically either.
I’ll explain what I mean by the term “micromanaging storyteller.” For example, I currently play one sim family and each family member has a fully fleshed out backstory. I create extra sims (secondary characters) and cheat reward traits to achieve the backstory I have in mind for a particular sim. I have a spreadsheet which lists all of my plans and goals for each family member, detailing their planned traits, hobbies, aspirations, primary and secondary skills (what skills do I want my sims to max, which skills should they at least attempt) educations, careers, etc for each of their applicable life stages (infant - elder). I also will list their potential love interests, residences, pets and offspring. Basically, if something is listed or found in a sim’s simology, relationship, skill or career panels, I’ve already detailed it all out in advance. Doing all of this planning is not only a fun and creative thing for me to do, but it gives me more opportunity to tell a story through my gameplay. After playing this way, I’ve found it’s nearly impossible not to get attached to my sims.
We each enjoy playing the game differently, so it’s really cool to read through everyone’s answers! :)
