US retailer GameStop will need to inform Californian customers about online pass fees associated with pre-owned games before they make a purchase.
GameStop stores will need to place signs on pre-owned shelves with all of the online pass information for at least the next two years.
The new rule is the result of a class action lawsuit that alleged GameSpot was misleading customers to maximise profits by not warning them about online pass fees, reports Kotaku.
"We are pleased that as a result of this lawsuit, we were able to obtain complete restitution for consumers, with actual money paid out to people who were harmed by GameStop's conduct," commented prosecuting attorney Mark Pifko.
"The in-store and online warnings are an important benefit under the settlement as well, because if GameStop discloses the truth to consumers, it is unlikely that they will be able to continue selling used copies of certain games for only $5 less than the price of a new copy."
A similar ruling could soon be made in other US states.
