Well here's the database entry for this release:
http://collectorsedition.org/game-db...-edition-ps3-2
My memory is vague though, and I can't remember whether this was a PLAY.com or HMV exclusive, or one which was only available from somewhere like Italy or Spain. Maybe someone else here can remember?
I would definitely be interested in a sealed World At War SteelBook though for X360 (if such a thing even exists)
