Create the lives you've always wanted!
Ready to live a freer, more creative life? In The Sims™ 3, you can let your fantasies run wild as you design your ideal world. Start with your Sim, refining each shape, color and personality trait until you get the precise person that pleases you. Design your dream home, but don’t let a grid limit you; place, rotate and stack furniture and walls freely and to your heart’s content.
Once the “hard work” is over, it’s time to be a mentor. Guide your Sim’s path through life, developing a career, finding love, and pursuing dreams and desires. Spending time with friends and family is just as important as mastering painting or accumulating knowledge.
Take things to the next level and record movies of your Sim’s adventures and share them with the ever-growing and thriving community. With a huge catalog of expansion packs and fun objects to discover, there is no end to the possibilities awaiting you. It all begins here; your adventure awaits!
