Gamer Stallion83 on Xbox Live had set a Guinness World Record for the highest Gamerscore at 317k points, but now has finally reached 500k points. He plans to reach 1 million points somewhere in the near future which is mind boggling. Can you imagine the sheer number of games that would have to be played to reach that kind of number. Say the average points per game were 1,000 that would mean that he would have to max out the achievements on exactly 1,000 different games to achieve that record. Anyways check out the video above of the achievement.
