A World of Warcraft player has completed all achievements found in the popular MMORPG. Many of you out there have likely done this with various games you have played over the years. However, World of Warcraft has 986 achievements. The player, Little Gray, has likely amassed thousands of hours in the game that many people just can't stop playing. However, he technically hasn't completed all of them, as a bug gave him credit for 2 achievements instead of one.
