However, Level-5 has issued a statement explaining why this new [EDIT: English language] version of the game will remain exclusive to the US:
Thank you for your interest in INAZUMA ELEVEN. We regret to inform you that LEVEL-5 International America, Inc. has no plans to release the Nintendo 3DS™ eShop version of INAZUMA ELEVEN in the UK regions. While this was a challenging decision, it was deemed unsuitable to release a game with American English voice acting in a territory in which the franchise has been so firmly established with the British English voice cast and downloadable game size constraints prevented us from including both English voice options. While we understand your disappointment, please know that this does not set a precedent for future releases. We at LEVEL-5 International America want to release our games to as wide an audience as possible and we continue to strive towards that goal.
We are truly sorry for the inconvenience and we thank you for your continued support.
If you want to play the first game, you'll have to track down a physical copy of the DS original. If you're in the UK, are you disappointed by this news? Let us know with a comment.
