GMG Region restricted key

dead island is usually restricted to NA, thats where amazon's is locked to

i buy dead island on green man gaming, and i am froum europe union and i activated it. Not play yet but i have in my steam library.

i buy it 2-3 months ago

I'm guessing... he's from germany?

Or he scammed you or it's region restricted,as you said,in his country

Maybe EU east EU west difference?

If it's the NA version, it can't be activated in the following countries:
DE NO SE FI DK PT ES FR IT AT CH LU LI BE NL IE IM JE GS GB IS MT LV LT EE CZ HU PL SK BG GR RO SI HR TR

i am living in Bulgaria so i am EU Region too and i activated the game verywell without any problem

i am from India and bought dead island from GMG and activated it successfully.

When I bought the 4 pack from gamersgate none of my mates (and me) could activate, so we need to ask for specific country key. /EU-2

I'm from Indonesia and I activated it successfully

it's possible to be NA only
