I have the original game disks for the Sims life, pet and castaway stores, is it possible that I can get these games on Origin as a download turning my physical copies of the games into digital or do I have to find another way to get them to work without the CDs? I have all the serial codes.
Pretty sure this only exists for the Sims 2, but you could try contacting an EA Game Advisor and ask.
