Account linked to gamecenter: is that a problem?

[MarsDarwin]

Hi,
I would like to sell my account on a game to which I can log in two different ways, either via my game account (email and password), or via gamecenter (iOS). I can't seem to remove the link with gamecenter. Is it still possible to sell it? Isn't there a risk that the buyer will refuse the sale because of the gamecenter link?

Some games do not allow unlinking. In those cases, you would have to provide the Gamecenter account in the transfer as well. If that is not a possibility, then the account should not be sold because the new owner would not be able to secure it.
