Microsoft has revamped its Xbox Live Rewards program, adding some new ways for players to earn credits for things they likely already do on Xbox One and Xbox 360. One of the changes is a new star system, which gives players higher rebate rates on purchases. You'll have to spend a fair amount of money buying things to earn stars, though - for example, members who spend $150 annually will earn one star. The star offers a one percent rebate. You can get up to five percent by earning stars, though Xbox Live Gold members will see that percentage amount doubled.
