My friend bought the game "used".

So as we were doing research into the matter we found out the key that you receive with the game is actually an account key, not an installation key, and the question arose that can this key be reused if the old account was deactivated? Does merely opening the box and not installing it make it “used”?

He bought it off of Amazon from Warehouse Deals Inc. which he says has a pretty good rating, but still this concerns us as the account key can only be used once.

So I guess what are the chances that he will be able to use the account key?

Thanks!

You cannot reuse a code. We will not free up a used account in order for someone else to use it. Our game does not require a monthly fee, and development of the game (and future updates) is paid for by a legitimate purchase of a game. We simply cannot afford to allow “pass-along gaming” by a dozen people on a single account, any more than a movie allows a dozen people to view the movie with a single movie ticket.
