I remember years ago, in my magazine days, I ran a story about the Australian gamers with the largest gamerscore. One of the questions we asked was this: would it be possible to hit 1 million points. Back then the answer was a resounding no. But today, it might just happen.
The world record holder for the largest gamerscore is Stallion83. At this precise moment in time, at time of writing, he is sitting at a gamerscore of 999410. He is 590 points away from 1 million. He could legitimately hit that mark in the next day or so. It is going to happen.
In fact, Stallion83 is livestreaming right this second. Head here to watch history in the making.
