Bought this key from Indiegala with some spare LTC that I found in a wallet. Better spend it now because the crypto market went to shit but this also means more GPU's for us gamers, yay! (https://imgur.com/A6hbKtE; https://imgur.com/mDX6YJp)
No region locks I assume as nothing was mentioned about it on the store page or when I went to reveal the key.
