I must say that people misunderstand this requirement. The Xbox Live is not officially supported in these countries (no services and support), but people from all countries can sign up as nearby supported country to gain access to online games and other basic features.
Please do not make fun of Microsoft for this, this is an old policy.
I'm quoting you again so more people can see it.
Is this the case, GAF? Can I play and enjoy the Xbox One in my third world country?
