Creativity (skill)

Creativity in The Sims
Creativity, like many other skills, is used only to advance in certain careers. It can be increased by playing the piano or painting a picture on the easel - as an added bonus, you can sell the pictures you paint, so a higher Creativity skill will mean higher value paintings. In Livin' Large, Sims can use the electric guitar, and other expansion packs released more pianos and instruments for Sims to use.

Creativity in The Sims 2
Creativity skill points can be gained by doing similar activities to above. Like the first game, you can still paint a picture or play a variety of instruments, such as the piano, guitar, drumset, or violin to increase a Sim's skill level.
