Create any Sim you can imagine, give them unique personalities and share them with the world. Then bring your Sims into The Sims 3 and be inspired with endless creative possibilities.
Create a sim is available on store and by digital download (in some coutries it's available only in digital download). It costs about 10 euros, and allow you to create new sim. This is not an additional tool, it is exactly the same Create a Sim available in the base game.
Create a sim is a sort of demo for who hasn't The Sims 3 and would like to try it before buy. If you have The Sims 3 installed, Create a Sim is useless.
