I'd love sports I'm not sure how a combined world would help beside eat up whatever pack it comes in budget and give us a very basic object/sport. We had bowling come in a stuff pack and its just horrible the Sims stand around lifeless if not playing even with the basketball net they still cant play a game together... If we get sports I want to see them play a game together and interact with each other Sims 4 still plays a lot like its built for a single Sim and that needs to change.
