My perfect sims game would be a lot more open.
-Open world, all careers able to be GTW style careers.
-Being able to have NPC jobs like paperboy, mail carrier, repairman, maid, bartender, etc.
-A working story progression.
-A more fleshed out education system.
-Being able to go to school/Uni with your sims.
-Being able to be a teacher/principal at any school/university.
-Being able to build your own University/school and also being able to build apartment buildings anywhere you wanted.
-Being able to visit/move to any world you wanted to without losing relationships like in the sims 4.
-Having sims with personalities based on traits rather than emotions. I want to see different reactions from sims based on a sims traits rather than their current mood.
- More fleshed out occult sims.
- More occult sims in general. (vampires, aliens, wereanimals, witches, angels, demons, elves, plantsims, mermaids, fairies, etc.)
- Being able to have vampire or witch covens as well as wereanimal packs.
- Separate family trees for said covens and packs.
-Hybrid children for occults.
-Being able to go to the past as well as the future.
-Graduation parties, baby showers, weddings, funerals, retirement parties, birthdays, prom, homecoming.
- After school activities that you could actually go to with your sims.
So basically just more choices, customization, and personalty.
