I did it! Hours of gaming have come to this! While it still isn't insanely large, its still impressive nonetheless. And I will shamelessly admit that the achievement that got me to 30,000 gamerscore was in Fifa 15 (which also got me too 10,000 gamerscore :)). How far am I willing to go? Well I guess we'll have to wait and see.
Edit: Didn't know this think updated automatically, but I now have 30,010 gamerscore. :P
Edit 2: I've been on a gamerscore streak recently. These past two days have netted me almost 500GS. Not too shabby...
Made a bet with LipeJJ and HylianYoshi that the XB1 will reach 30 million before Wii U reaches 15 million. Loser has to get avatar picked by winner for 6 months (or if I lose, either 6 months avatar control for both Lipe and Hylian, or my patrick avatar comes back forever).
