Hello Nutemekiset1,

You can earn Xbox Live Rewards Credit in two ways:

1. By finishing the offers located on the MyMissions page at
https://rewards.xbox.com/mymissions/ .

-or-

2. For non-offer purchases, you can earn Credits by earning a one star MyVIP level through purchasing at least $300 USD or regional equivalent of eligible content. After you receive your first star you will begin to earn a percentage of your eligible purchases
back as payback Rewards Credit. Pre-orders, in-game consumables, and subscriptions are not eligible for MyVIP.

In September 2014 we changed to the MyVIP policy. As a result, payback based off Gamerscore (MyAchievements) was discontinued. Also, as of July 2014, we do not award Credits for Xbox Live Gold renewals. MyVIP has a recalibration every year. At the end of
the year, we place you in your MyVIP rank for the new year based off your eligible spending from the previous year, and set your progress to the default state. This happened in September 2015 and December 2016. Since you are a zero star member, you do not
get payback Credits on your purchases. You can check your current MyVIP level/progress at (https://rewards.xbox.com/myrewards/).

I think the game is also amazing, but I think it's very likely he'll receive many, many awards

I also haven't received The Game Awards 2018 Mixpot. Is this where we should ask for help with that?

I love both the Splinter Cell and Metal Gear series, but wow, you can't really compare the two. I would never say that Metal Gear is over-rated. At least in my opinion, this is one of the best series on any console and the reviews anywhere you look reflect
it. MGS4 Guns of the Patriots was awesome!!
