If you aren’t familiar, Xbox Rewards is a rewards service, a way to participate in Xbox events to earn for-reals Microsoft Points to redeem on the Xbox Live Games Marketplace. It’s a cool little concept.
If you are familiar, and further, have actually joined, then hooray! You’re getting an extra avatar item!
In an almost Orwellian way, the shirts say “Xbox [heart] You”. And apparently it does. This seems more sincere than most, since the rewards program actually costs no money.
However, if this was a shirt to be paid for, there might be unfortunate implications from the shirt’s message.
But otherwise, enjoy. Xbox loves you.
