My year 3 of owning XBOX ONE
I have earned 46,650 points worth of gamescore(2-16-2016-2-15-2017). I earned 20 challenges in that time period. That is 4 more then my first year of owning XBOX ONE. And all my year of owned XBOX ONE. I earned 109,628 points worth of gamerscore. And earned 40 challenges in that three years. I can see myself get half way mark to 200,000 points worth of XBOX ONE gamerscore. But it a big if.
