What is mindboggling about this is that the UK is considered a seperate region to the rest of the EU, possibly breaching EU consumer standards. A UK copy of the game bought in a Irish town lying along the Ireland-UK border cannot be installed and registered on a Republic of Ireland Steam account! Amazon.co.uk said they were only informed this morning; they've changed their online description accordingly and said they would contact customers looking for a refund. Other retailers such as Gamespot Ireland are still looking for clarifications."
