It would appear users who are paying to use Xbox Live, Gold Members, are being rewarded with a “special gift” during their birthday month if the user in question has a game score of 3,000 or higher. If the user has a score higher than 10,000, they are receiving a 1% back on Microsoft Points they spend each month. A game score over 25,000 will get you 2% back on your points. It should be noted that the maximum amount of points you can receive back from the program is 30,000. What do you say about the reward system, does it seem like a nice reward for playing games?
