Level-5 and Sony's PS3-exclusive White Knight Chronicles franchise never attracted the same kind of fanbase of, say, Demon's Souls. So, the online servers for both WKC 1 and 2 are being closed rather unceremoniously on June 18th.
A notice on the forums confirms the date, and notes that offline play will be unaffected by the server closure. "Thank you for your support till now. We hope you will still enjoy playing offline," the posting says.
Although the post only mentions the first game, its sequel will also be shut down on the same day, according to a tweet from the PlayStation account.
