Summary: Sims 3 Generations definitly doesn't qualify to be an expansion pack- you don't get a new town, any major changes to game, or any new buildings. It just comes with one park that's pretty ugly and doesn't fit well with Sunset Valley or Riverview. I would classify it more as a stuff pack. It gives you plenty of clothes and new furniture. The new actions that it provides you with are boring and even a bit annoying.
Summary: I usually buy the game itself but I thought I would download it this time, Big Mistake! I'm not saying this would happen to everyone but for me it was disappointment after disappointment. I have a 15" MacBook Pro and all the specifications for this download including high-speed wireless internet, and the download took 6 hours!
Summary: Game does not change much of the play. There are new scenes, but they really do not change much. I bought the product because I thought that it would have either a new town or a lot of new items. This is not a Maxis game anymore so since that happened I have not seen the same quality of the games. If you compare the game to my other extension packs, I think it lacks in that area. The Sims can do all these things this expansion pack just gives them props to do it.
Conclusion: This expansion has less 'in your face' features than any others. Upon installing, I started a new family from scratch. After 5 or 6 hours of play time I am yet to notice a difference between this and the base game. That said, a friend of mine who has an established neighbourhood has enjoyed the subtle changes this brings to each life stage.
