(Currently U.S., Canada, United Kingdom, France, Italy, Germany, Japan, Sweden, Singapore and Spain)

What languages are supported?
You can localise your games into English, French, Spanish (of Spain), Italian, German and Japanese. It is NOT mandatory to translate when you release to a region though it may help sales. Note that it will also likely slow your review. See Language Review issues

When will {my country} be supported?
There are currently no additional countries announced - please don't keep asking in the forums it doesn't change anything. Watch the XNA blog and news page.
If your country does not support Xbox Live then its not going to happen any time soon. Sorry.

Can I work around the system?
No.
Many folk ask what is needed to work around the system? An address? A bank account? Tax ID?
We don't know for sure and if we did we wouldn't be posting in in here - its unsupported and Pheel says "don't think of doing it because then we might have to ban you"
The only supported 'workarounds' are 

• Move to one of the supported countries and fulfil the financial and tax requirements for that country.
• If you work on a team and one team member lives in valid country then they can submit - its up to you to work out how to share profits and don't forget the person who submits deals with the taxes.

Anything else you do is at your own risk, unsupported by Microsoft and may have consequences for your account and your game...

Why is it not available in {my country}?
We don't know. Microsoft don't say why. It may be due to financial, legal or just simply not enough time. Remember that its a complex process that involves game ratings, international money transfers and taxation and therefore lawyers, accountants and even possibly politicians so you can image the trouble that causes!
