Just a heads-up to anyone trying to buy the Sims 2 Ultimate Collection from online (especially Ebay):
WARNING: DO NOT BUY THE ULTIMATE COLLECTION ON EBAY!!!
There are numerous listings for The Ultimate Collection on Ebay and they are dirt cheap – usually just a few dollars. When you dig deeper, you find out these are actual Origin accounts being sold with the Ultimate Collection on them. After you pay, you’ll be given a username and password for an Origin account. Many of these are stolen accounts.
Origin WILL figure out this account was stolen and it will be revoked. You will lose your money and the access to the game. Even if the account wasn’t stolen, it’s still against the Terms of Service to sell an account, and will eventually be revoked.
And finally, you can also be scammed by the seller changing the password after selling you the account and re-selling it again. Or even claiming to Origin that YOU hacked the account and getting it back. This is NEVER legit. DO NOT BUY THE ULTIMATE COLLECTION ON EBAY. Only buy the physical disc from reputable sellers who include the CD key and have a picture of the product.

In general a digital version of the Sims 2 was never made so the only trustworthy way to get The Sims 2 is buying the discs.
