A portion of a review by GameZone:

Audio is as strong in World Adventures as it has been since the original release of The Sims 3. Of particular note is the music, a somewhat cheap but effective device, which helps drive home the distinct flavor of each region. Graphically, it’s hard to say if The Sims has ever looked better. Intricate use of color and a fairly clean aesthetic makes things very easy on the eyes, and even the bronze lion statues look pretty darn good. Essentially, World Adventures emphasizes new gameplay over simply a few extra collectibles, and that is what makes it so successful as an expansion. If future efforts receive similar levels of attention, Sims fans will have a great deal to look forward to.
