Fastest Xbox videogame for achieving 1,000 Gamerscore

Gamerscore is the accumulated points tally based on a player completing achievements in an Xbox 360 or Xbox One game, with most games offering a 1,000 points max. Typically, reaching that score takes many hours of gameplay that requires considerable dedication and skill from the player. In a video published to YouTube on 12 February 2008, "Georat1101" demonstrated that "1,000G" could be accomplished in the Xbox 360 action-adventure Avatar: The Burning Earth (2007) in less than two minutes.
