For me what is not to love?
The Reputation System and the Fame System alone is already worth the 40 bucks. The challenge it had to build up your reputation and your fame is already awesome! The fact that you can progress your reputation level and the world change around you based on your reputation is awesome, and will result for good and bad sims having a lot more depth when it comes to gameplay. I haven't played the Acting Career yet(and tbh, I only bought if for the reputation) yet these two system are a huge game changer. This pack reminded me of Get Together. This is one of the features/Packs that is very hard to show off, but once played, without cheats, that is where we started to see how big it is, and how deep it was adding to the gameplay. I don't care about the size of the pack.
If a pack appears small then I'm fine with it as long as it changes gameplay and adds new opportunities for expandable gameplay rather than a huge pack that has so many features that I will play only once. My hope, is they add more systems into the game that contributes to sims personality, and integrates a lot of features that we will and already had to provide us the best level of experience. Congrats on The Sims Team.
