Just spotted it: the steelbooks from the EU versions are slightly different to the US in the special and collector's edition. But as far as I can tell it's only the spine. The EU version has the name of the game in an standard arial like font like all other Sony games in Europe. The US version has also the name on the spine but stylized with the font of the game like all other Sony games in the US. Don't know why they are doing this in the first place for like ages but that's another topic.

There are also some differences in the packaging. The steelbook in the EU version for example is y-folded sealed.
