Summary: I love this expansion. While some things can get annoying, like solicitation from the game to get enthusiasm for a hobby, it's optional to subscribe to hobby magazines. Overall, this expansion definitely adds a lot of playability to the game, not just with hobbies, but with Sim's aspiration rewards as well (in the form of passive abilities that can always be changed with the personality changing Aspiration Reward).
Summary: If you have a windows 7 computer do not buy this product. The product will not download and EA is not attempting to fix the problem anytime soon. This product works well with Windows XP, and I'm not sure about Vista.
