music | get money bitch.
the question is what don't they do tbh

here's the list the best one is story progression because it allows neighborhood sims that you aren't playing to actually DO things, they'll get married and have kids and get jobs and divorces and move around that enhance the gameplay for you because your town will always be evolving. you have a ton of things you can customize, like increasing the chances for a gay sim, allowing teen pregnancy, allowing you to rename all the babies in town, changing school types. master controller (with the cheats addon) is also fun because you can view additional information about your sims or sims in town, edit their skills, families, cash, job, change their name.
