Elsewhere, Sony has confirmed that the PS Plus edition of DriveClub will not count as one of October's free games for the service. It will instead be a bonus on top of the planned PS Plus offerings for the month.
"Driveclub will be in addition to your regular PS Plus allocation," stated PS Blog manager Fred Dutton. "There's loads of content included. Do try it out: I think you'll have a great time with it, and at no additional cost to your wallet."
