Gamerscore is a numerical value that measures a player’s achievements in Xbox Live games. It is calculated based on the number of achievements a player has unlocked, as well as the rarity of those achievements. A higher Gamerscore indicates that a player has spent more time playing games and has achieved more difficult goals.
There are many reasons why a player might want to boost their Gamerscore. Some players simply enjoy the challenge of unlocking new achievements and increasing their score. Others may want to earn rewards that are only available to players with a high Gamerscore. For example, Microsoft sometimes offers exclusive content or discounts to players who have reached certain Gamerscore milestones.
