We’re pleased to announce that all players who purchase the Southeast Asia/Australia/New Zealand version of StarCraft® II: Wings of Liberty™ will also have the option of playing on North American servers following the launch. While we still encourage gamers to play on the local servers, which will offer lower latency and more action during peak hours, we recognize that many players have longstanding friendships and rivalries with North American players, and would like to continue playing with them. Because of this, we're giving Southeast Asia/Australia/New Zealand gamers access to both regions' servers, so they can choose where they'd prefer to play.

This additional access will go into effect as soon as possible. Our intention is to make it available within 60 days of launch -- at that time, players with a copy of the Southeast Asia/Australia/New Zealand version of StarCraft II: Wings of Liberty will automatically gain the option to download the North American version of the game client through Battle.net®. You can check out the FAQ for more information, and we’ll have additional details to share about acquiring the North American client in the near future on our Southeast Asia/Australia/New Zealand community site.

AdmiralThrawn, it says your character doesn't exist.

I'm in the US. If you are in the UK, we can't play together.
