Re: Sims 4 Multiple Downloads

If they used it once, then it's registered on their Origin account so yes, they would also need to sell you their Origin account. You need it to play, not just to download so I would not bid.

Both the Sims 4 standard and digital deluxe edition is currently 50% off at Origin: https://www.origin.com/store/buy/sims-4/mac-pc-download/base-game/standard-edition

The limited edition is no longer available through Origin though.

You can see the differences for the different editions now: http://sims4.crinrict.com/en/2014/01/editions/
