Consider this: The Sims franchise is the best-selling PC series in the world. Yes, bigger than games with the WarCraft name. Stack it up against console games, and The Sims' global sales are second only to titles that bear Mario's moniker. Yet many gamers still seem to associate The Sims with its dollhouse parts -- clothing packs, furniture exchanges, MySpace pages with soap-opera movies -- forgetting that there's an intricate game there, too. With The Sims 3 (teased yesterday), Sims Studio head Rod Humble and his team are trying to bring that aspect back to the front.
