Which do you use to run your Sims 3 game?

I didn't install everything in my game from disks. Some of them were by download from Origin, before they changed it so you can have to play through Origin. That is something I will never do. So to make sure it would never be necessary, no matter what, I re-bought everything on disk that I'd previously bought by download, including a disk copy of the 2009 base game. I started playing in 2012, with Amazon downloads of the base game, Generations, Ambitions, and High End Loft, so I didn't even have a disk of the base game itself, until I bought the starter pack on sale to get Late Night, for less than I could buy it for on download from Origin. It was expensive, but it was worth it.
