Xbox Live Gold Question

[remnant]

My xbox live gamertag is an SA one.

If I buy a 12 month xbox live gold subscription does it matter what region I buy it for?
Or are all Xbox Live Gold subscriptions Worldwide?
Or...does it work that when you buy a Worldwide subscription it has the ability to work with any region but when u activate it, it becomes the region that your gamertag is?

The reason I ask is because either i need to pay R265 for a 'SA' subscription from TakeALot or R375 for a 'Worldwide' subscription from www.mspoints.co.za.

Also, if i buy an SA subscription does that mean I can't play online against anyone from another region or can any region play with any region? Do most MyGaming forumites, who play on xbox live, have an SA or a UK subscription?


UPDATE: I emailed TakeALot and they confirmed that it is a Worldwide Subscription and not an 'SA' Subscription. The product page on their website has been updated with the "SA" being removed.
