Honestly, if I could only pick one, it would probably be Strangerville. The adventure can be replayed, and the pack can be used afterward as just a normal world if that's your preference. I love that things in the world change afterward, like characters talking about the changes that have happened to the town. It comes with a lot of unusual Build and Buy objects. It's different having a bar filled with military personnel. I also use Get to Work and Cats and Dogs a lot.
