I believe this key works and has no region restrictions, but I cannot guarantee it. If any problem arises, I'll do my best to replace the key, but I can offer no guarantees; in particular, if it turns out there's a region restriction, there's nothing I can do. Should I be unable to replace it, I apologize, but the winner will have to agree to delete the giveaway. If you don't agree, please don't join this giveaway; thank you for understanding. Good luck to all and I hope the winner enjoys the game.
