Build-a-City Challenge, Sims 3 Version, Fixed for all EPs

Postby clyson » November 8th, 2015, 10:02 am

I was really surprised not to see the BACC sims 3 challenge here yet so I'm going to add it here

:alert: This challenge isn't mine you can find the challenge at

The link for the supported mods is here:

Sim Customization:

This is optional, but I feel it adds a bit of spice to the challenge.
Roll a 6 sided dice once;
If the number is even, the sim is normal, if the number is uneven, roll again to determine species.
Roll a 6 sided dice for determination of species;
1,2 is human, 3 is werewolf, 4 is fairy, 5 is witch, 6 is vampire

Roll a 6 sided dice once for lifetimewish determination:
1 is wish 1, 2 is wish 2, 3 is wish 3, 4 is wish 4, 5 is wish 5, 6 is a reroll.


Create a new neighborhood and bulldoze all the lots. (You can leave one lot, which is a garden with seeds in, must set the type to No Visitors Allowed. Your Founder may get seeds from there every Sunday, or place a Harvest Stand, that your sim can buy from every Sunday.)

Make eight sims that you will not play (4 males 4 females. Make four of them be in couples - 2 couples 4 singles, no homosexual couples, as these will populate the neighborhood too). These will be your NPCs. Move them into a big house. Your sim may only visit them once, greet them, and then leave. You may first visit them again when you've become best friends with one of them. You have to randomize their traits, and lifetime wish. They count towards population.

You may not move in NPCs, and then move them out again.

Make your founder. Your founder has to move into an empty lot, and he/she cannot get a job unless you manage to unlock one. You should survive with Fishing or Farming. Your founders purpose is to reproduce.

You play each family one week at a time. You can leave Story Progression on. NRAAS Story Progression mod allows you to choose what can happen in the city with Story Progression, so you game does not get "bugged".

Score and Population Calculation:

Sim Multiplier (SM)
Your sim multiplier starts at 1.
+1 for your first community lot
+1 when you reach a total of 5 community lots
+1 for every 5 additional community lots
+1 when the first Sim invests in a business (see the Investing section)
+3 when 4 businesses have Investors
+5 when all 11 businesses have Investors
+2 when the first Sim owns 1 business outright
+6 when Sims own 4 businesses
+10 when all 11 businesses have owners
+5 for each Airport

Actual Population:
# of Playable/NPC sims X Sim Multiplier (SM) = Population
In words: The sims you play combined with the NPC household times the sim multiplier equals the population of the city.


Reach 50000 population.

(More to come...)


Now, I cannot stress enough that you should get NRaas' mods, I am gonna explain which, and why:

You should get this as it allows your inactive sims to have children get married and other things much more effectively. It also allows tinkering with all of the things it effects, example: You have a town. You can go into click on your sim, choose NRaas, Town Options, and you can turn off Marriage, that way sims will only marry if you command them to (Lots of other options). Adds to realism.
This mod makes sure that your NPC sims actually repopulates.
Gives way more diseases that your sims can get, which could make you get a hospital faster. It also adds to the realism.
This will make inactive sims gain Lifetime Happiness points from their wishes, even when not controlled by you. This makes the Story Progression more useful.
For the obvious reason that I made rules for them. They just add a bit more variety for your sims.
Your sims won't wear the same thing every single day, so if you want your town to be more realistic, this is good too.
This mod is especially important because it every once in a while asks you to save. The BACC takes a bunch of CPU power, so incidentally, your computer could end up crashing. But if you save a lot, you won't loose much!
It allows you to sell things like pets for money. It simply adds more ways to earn money without a career.
And finally:
You can use it to turn off immigration to the city, which is crucial. Immigration takes empty jobs in your workspaces, and moves in sims in your houses, that are unpopulated.

And....that's it all, I did was copy and paste, edit some grammar mistakes and add the bb codes. Enjoy this challenge! :D

Quick question. When the criteria is met for the jobs do we then put down the building in which it corresponds with? Or can you start with all the buildings and you just cant get a job there until you met the criteria? TIA
Edit--- Also to unlock the bookstore, does it have to be 5 skills maxed by one sim or can it be from many sims?
