Microsoft Points to purchase games, videos, add-ons,or themes and gamer pictures.
Xbox Live Gold Membership and Microsoft Points are two separate things altogether. The 1600 points you are refering to are Microsoft Points, used to buy Add-ons, Xbox Live Arcade Games, Premium Themes and the like. This is completely independent of the Xbox Live Gold Membership, which deals with Online Play. In order to utilize Xbox Live Gold Membership, you must either buy a pre-paid card which states the amount of time you are buying, or initiate a pay plan with a credit/debit card. In short, assuming you are looking for Online Play, the 1600 points you purchased are useless
Yes you do because you can only buy things from the market place if you have points and marketplace comes with xbox live
Yes...
with a credit card or go to a store and buy a Microsoft points card.
Yes but you will need to buy a Microsoft Gold Membership for playing online versus other people.
Nope. Credit cards on Xbox LIVE let you buy Microsoft Points and Gold Membership right off of your Xbox. You can buy cards at game stores, and some game stores let you Pay with cash. Codes on the cards can be typed on your Xbox, and you get the same stuff from that. So Credit cards let you get Microsoft Points and Gold faster. But you can get cards, so you don't need them.
The only way to obtain 1600 Microsoft points is to buy them.
Yes you may.
No. You earn gamer points playing games, Microsoft points are to buy things on the xbox live market place.
4000 points is the largest you can buy in the US.
