I saw a comment on CD-A forum which said "Thanks CD-A for no region locked key" but maybe... Anyway, I can go first with key, and trader will see how it will work for him. :>
I think Ateszmadman is right http://cdr.thebronasium.com/sub/17730 "onlyallowrunincountries = PL"
This is a polish premiere thats mean no one of polish distribution block game, also guys from cd-action says "there is no regional blockade" It also english language version.
All of the following:
