At last, the Xbox 360 Gamerscore is no longer just for show. Microsoft’s (MSFT) Xbox Live Rewards program is now giving gamers special perks for having higher Gamerscores. Rewards are split into three tiers: Contender, Champion and Legend. Contender rewards gamers with a Gamerscore of 3,000 to 9,999 with a “special gift” during their birthday month (the prize is only worth $0.25 and is likely an Avatar item). Champion-level Gamerscores between 10,000 and 24,999 will be rewarded the special gift and 1% rebate on Xbox Live Marketplace purchases every month. Read the full story at Boy Genius Report.
