The ability to bring a character to life, to tell a story, and to move Sims to tears is a genuine art. To these artist, life is a canvas.
Sims can build up the acting skill by practicing in front of a mirror or a microphone. Sims can also read skill books on the subject. As this skill increases, Sims will be able to perform scenes in public, and for tips to make extra Simoleons.
At Level 4, the The Trouper's Looking Glass item is unlocked, which helps Sims learn the acting skill much faster.
