Look at: https://steamdb.info/app/2322010/subs/, all packages are either limited to small regions or not available in ~175 countries. Even the "Rest of World" preorder package.

That's because the game needs PSN which is not available in ~175 countries. Even if the key is global, if the winner from a non-PSN country activates it, they will not be able to play. There is a mod floating around that removes the PSN requirement, but it may become useless after an update.

Not available in Lithuania, when I open up the steam page.
