This is NOT the GAME, it is EXTRAS for the Sims 8 in 1, it includes the ELUSIVE magic bookshelf which stores Makin' Magic ingredients, making it possible for adults and children to swap ingredients, also includes Dorm furniture, and the McDonalds Kiosk for public lots.

There are 2 types of files. Installation instructions & a thank you note are included. You can download 7 Zip for free if you search for it in order to open the zip folder. Honestly if you're on TPB, there's NO REASON you shouldn't have it by now, but this is just to save any nabs the embarrassment of having to ask how to open a .zip file >.<
