On a warm spring afternoon in EA's sprawling San Francisco Bay campus, the Sims is described as many things. It's a commercial phenomenon; it's the PC's most successful game; it's second only to Mario as the world's top-selling game series. It's a business unit; it's a business model. It's a creative tool; it's a canvas for the player's imagination. It's a private form of self-expression. It's a community. As you may remember, The Sims is also a game - one of the most popular, successful and, yes, innovative games in history.
