What aspect of the Sims 4 do you enjoy most?

I enjoy all of them so I can't pick just one. Ultimately, gamepack is the most important, but I like to make my own characters and houses for whatever game I am planning. Unfortunately I have been busy in rl so have spent most of my time, when on the game, building. I need a good stretch of time to actually play and right now deal with constant interruptions, which don't bother me as much if building. I am currently planning to set up two games, one supernatural and one without, and am working on my characters and houses for that. Hoping things quiet down with summer coming so I can actually spend time playing after setting up my games!
