Can I play the sims 4 with the same disc my sister used already using a different code?

4 Answer(s)

Yes

Yes you can. Once you've purchased the disk, you can install and play it on an unlimited number of computers (But you will need the disk to actually play after installation, of course).

No

The discs are all the same, they are not linked or paired to any specific code. As long as you've got a valid code added to your Origin library, you can use any Sims 4 disc.
