The Xbox 360 port of Final Fantasy XIII has been confirmed as being almost half the size of the PS3 version, coming in at 18GB on 3 DVDs versus 38GB on one BD, far smaller than expected.
The comparison comes by way of review copy:
Disc 1: 5.9GB
Disc 2: 5.8GB
Disc 3: 6.6GB
Xbox owners will likely be hoping careful movie compression will limit the difference, but obtaining over 50% compression without a significant loss in movie quality is not very likely.
More problematically, preliminary reports are already showing actual in-game graphics have suffered on the Xbox 360, far from reassuring news for what was supposed to be an “absolutely identical” port.
