This WAS a pretty good guide to Sims 3, but unless they have updated it, it won't be current to the many, many additions that EA has done to the game. I don't even mean add-ons, either. They have updated the base game so much that I don't think that this would help anyone that much.
Extremely helpful in all areas of the Sims 3. You sgouldnr have a sungle question after readung this. Its also very easy to use as a reference. I absolutely live it.
