Portion of a review by Den of Geek:

In the span of just over a week of playing of The Sims 3: Ambitions, I haven’t encountered what I would consider to be any serious bugs.  The graphics have moments of drawing really slowly, despite the game being run on my more than capable machine. White blocks will appear instead of the textured buildings, but they will slowly fill in the detail. It doesn’t happen all the time, but enough to be noticeable and more than just a one off.

There also appears to be some issue with the stacking of tasks when in career mode, with the Sims often being told more than once to do a task. There haven’t been any crashes to desktop, though, and when I took my characters on a vacation to China through the World Adventures pack, they all came back alive.

After so long apart, the world now feels a slightly better place now that my love affair with The Sims has been rekindled. Sure, I will always carry with me a slight suspicion that it might betray my loyalty once again at some point in the future. For now, though, I am willing to have faith that any of those little niggles will be smoothed out by a patch and the game itself will continue to go from strength to strength.
