Hi elasticote,
How do i get the Microsoft point and how much are they selling for?
TQ
Generally as a rough guide 400MSP=USD5.
Since you've got a US Gamertag, there are a variety of online outlets where you can get your US MS points. Amazon.com (but they only sell if you have a valid US address), Play-asia.com or offgamers.com all have online codes which can be redeemed on your console or on xbox.com. From what i can tell 4000MSP is currently selling for RM155-165.
Asian Xbox points can be easier to find since you can find them at retail outlets such as gamer's hideout. They tend to be more expensive though.
Having said that, MS recently added paypal as an additional payment option so you could try that. I don't have experience using it so I'm wary of giving advice on that.
Games can be purchased via the 360 dashboard once you have points or via the marketplace on xbox.com. Purchases made on xbox.com will automatically start downloading the next time you log on to your xbox.
What you'll find is that most XBLA are not region locked so it really doesn't matter where your gamertag is based. However, there are some exceptions though not really worth worrying about.
Any XBLA game you purchase will be available for any gamertag on the xbox you originally downloaded to. However, if you move your hard disk to another xbox, you will need to be connected to live on the account that you used to make the purchase and will not be available to other gamertags on that new xbox.
If for example, you do get a new xbox and want to transfer all your DLC and XBLA that's no problem as well, you can get a license transfer (last i checked this can only be done once a year) to enable all the DLC and games on that new xbox to be playable offline and by anyone on the new console.
