While The Old Republic is only initially launching in select territories; it doesn’t matter where you live in the world if you want to play it on launch day. BioWare has confirmed on the game’s official forums that the MMO will not feature any sort of region locking so if someone lives outside they launch territories, they can import the game and still be able to play it:
There are no plans to ‘region lock’ or ‘IP block’ players from the game. You may experience some latency issues if you’re not playing in a launch territory.
So if you don’t live in the US or UK, you can rest easy now as you’ll be able to play The Old Republic when it releases in a couple of months.
