Go get that easy XP while it lasts. Some extremely long achievements are tied to getting XP, I still need the level 100 myself.
I wonder what they will have in store next? Play Gears of War 2 and get free money weekend? At this rate that may just happen.
I feel really bad for the folks that went from 1 to 100 during normal XP. HAHAHAHAHA LOLOLOLOLOLOL pwned like this.
