World of Final Fantasy is already a nostalgic golden nugget for Square Enix veterans, but the fan service is about to get even stronger with the addition of Sora from the Kingdom Hearts series. The Keyblade-wielding icon will be added as free downloadable content later this winter – but only temporarily as a means of commemorating the release of Kingdom Hearts HD 2.8 Final Chapter Prologue.

"Sora will be available for download for a limited time only, appearing in his Kingdom Hearts Dream Drop Distance HD outfit," the press release explains. "Further information on how to obtain the Sora champion summon will follow at a later date." Is this something that you'll be downloading?
