OK, so it's technically impossible to beat a game that has no defined ending,
but World of Warcraft player "Little Gray" is the first to finish virtually
every single thing that the land of Azeroth currently has to offer.
According to MMO Champion, he's the first player to nab every single
achievement in the game and the first player to reach 986/986 points listed in
the armoury.
His stats in the armory show that he's killed 390,895 creatures, and died
just 8,543 times. He dished out 7,255,538,878 points of damage to his foes, and
completed an average of 14.6 quests per day for a total of 5,906.
