Final Fantasy XIII Xbox 360 install is at 18.3GB, completely optional

If you’re one to install those Xbox 360 games of yours to the console HDD then you better make sure there’s room for Square Enix’s FFXIII.

Three discs will demand 18.3GB of space should you opt for it. Final Fantasy XIII releases March 9th in the US and EU for Xbox 360 and PS3.

The report comes from VE3TRO, who points out the obvious bad news for Xbox 360 Arcade owners. While technically it should fit on a 20GB, it won’t because of needed cache space (6GB) for the console to function.

Disc 1: 5.9GB

Disc 2: 5.8GB

Disc 3: 6.6GB

Final Fantasy XIII releases for both Xbox 360 and PS3 here in the West. Are you one to install Xbox 360 titles to spare yourself noisy disc drives, or preserve games?
