IF I could make a sim simulation game this is what I would have:
In CAS there would be a butt slider and leg sliders. Oh and tooth design sliders
There would be of course clothing, but as part of clothing there would be an underclothes section. There would be a pre-teen stage (that I will explain down below)
(next part would be a bit contversy):
There would be one very special button..this button allows you have to the D word sims. If you press this button, you get access in-game to ramps,elevators and special kind of stoves, showers and compailty buildings. But if you don't want the D word sims just don't click on the button. (this is the only way that you could get D word sims in my version of the game if I could make one), using this would get an additional sliders that allows for hearing loss and which ear. (of course there would be an option at the start of the game whether you want to play a town with both disabled and able bodied sims or no disabled sims at all.)*
traits/personality
Here are some traits idea me and someone from another website thought up off (and we would also have personality points)
Ambitious-would want to get As, and if they have dramtic trait too would want to get lead role (and if evil or mean sprited might try to sabtoge the real lead's role)
Artistic-creative projects for homework and doodle in their notebooks during lunch hour
Athletic -want to do all sports no matter what the sport is. (has a chance of broken arm/leg)
Bookworm students tutor other kids and maybe get paid to do homework
Clumsy- spill food/drinks on the floor, accident break objects, and with a Pets EP cause a mess of pets' water.
Daredevils- play with fire, do dangerous tricks on bikes,snowboards, skilling,etc (can have a chance of a broken leg/arm)
Dramatic students-put on plays (if there is more then one major competion)
Evil toddlers-can draw on walls (and maybe older adult sims can kidnap others-I have more thoughts about kidnapping idea later)
flirty sims are more concerned with finding a bf/gf than school work or anything else
Genius students tutor other kids and maybe get paid to do homework
Hopeless romantic-want to find their one true love
Would love for more ideas for traits.
Their would also be personailty traits like the first two sims games
*if the kid is born in-game they can earn or loose traits.
ingame:
There would be jobs of course. Journalist would be sent to "the field" to cover stuff. Journalists could sometimes get chased by dogs or on a rare occasions a poltican.
Polictians could actually set up and have sim elections (all the sims would go to vote for their choice), and make real decisions. Law Enforcement go around and keep the crime low? Doctors (think its fine), Military is fine (the only idea I have might not go over well.) Culinary is fine, Scientist (maybe trying to find cures for the diseases--not anything serious in my version of the game). Musicians are fine. Authors could have book signings at the book store.
*supply teacher would not be part of the Education career but the being paid would amount to how many days you were called in, in a week.
There would be a bakery, a candy store, a mall, restaurants, of course grocery store (this would have shopping cart where you're sim can place their food and if they have a small child they can place the child in the front of the shopping cart, but there would also be little toy shopping carts too for toddler children) & book store (yes these would be non-rabitholes but for the restaurant there would be a bit of a rabbit hole, the "kitchen" is the rabbit hole. You could buy out and run them yourself you would be able to set prices, hire employees, there would be little chance cards about problems employees are having and you have to make the right descions).
Movie theatre: get to chose what kind of snack/pop your sim want to eat/drink (or decide just to skip the snack and pop and wait until after the movie to eat).
weddings:
You can either have hire a event planner, or plan your own wedding. You would chose who would be bridesmaids, ringer bearer, flowergirl, and hire a caterer (I have another idea, that you can be a careteer or a event planner..but I still working on that). Or if you sim has parents, the sim mom could cook your wedding cake and supper, and sew the wedding dress).
babies:
you can chose whether sim moms could breast feed them or just stick with the green glob of milk bottle. (note:sim mom who breast feed their babies are less likely to get diseases). Babies aren't swaddled up. The have legs, and you can dress them in cute little outfits. Sim moms/dad/grandparents/older siblings can sing to them or rock them in the rocking chair. Yes bath them too.
Toddlers you can chose to still have sim mom breast feed or if your kid is on the bottle move to a sippy cup. (they can still move to a sippy cup if you started off breasting feeding) Toddlers can steal the other's cup/bottle. If there are twin or triplets, they have more "connection" with each other. (through out life). Also get floaties.
Children
mostly the same (expect being able to help with gardening and using the microwave and toaster and can use the stove with parents' supervision and able to play instruments). There would be a playhouse and a play kitchen. costumes: dragon, teacher, bride, dancer). and toy cash registers that could even look from a Western movie or from modern time.
pre-teen
can have crushes, but get embarrassed by someone coming in and see them playing with "childish" things, can cook with the stove without supervision, but can only cook very simple things
teen
can get acne, sneak out, cook more fine things
Young Adult:
can go college (you can live at home or live in res, well living in res there would be cooking classes, and other how-to-live-on-your-own classes), and yes in this case YAs at college can become pregnant.
Business
Health
Hospitably**
Science
drama
Adults can chose to take a class @ the college
Elders can also take a class @ the college
There would be the option to give up a baby for adoption.
school:
there would be 3 schools
elementary school and children would 1)learn skills there and 2)bring home assignments for specific classes (which you chose on the child aging up to child, from toddler). There would be events like 'bake sale' at the school. oh and there would be recesses for children.
middle school, tougher assignments than elementary, but not as tough as high school. and learn skills.
high school more difficult assignments and learn skills
