Reports online are indicating that Square-Enix’s upcoming Xbox 360 version of Final Fantasy XI will only be playable if you’ve got a hard drive jammed onto Microsoft’s next-gen machine. The massively multiplayer version of the popular RPG franchise has already enjoyed widespread success on the PS2 and PC - despite the fact that the game never saw a European release on Sony’s machine. In fact, the 360 version will be the first to hit consoles on European shores, likely meaning a lot of fans will be eager to pick up the title at launch. However, the news that a hard drive is required to play is likely to come as a blow, not only to FF fans intending to snag the cheaper, hard drive-less Core version of the 360, but to Microsoft itself. Since the announcement of the dual packages, the company has been insistent that a hard drive won’t be mandatory to enjoy next-gen titles, but that the inclusion of one will enable developers to offer slicker, enhanced gameplay experiences.
