A city in New Mexico where 1,300 unwanted vintage video games were discovered buried in a landfill has voted to auction off more than half of the cartridges in the run-up to Christmas.

Members of the Alamogordo City Council voted 7-0 late on Tuesday to offer some 800 of the Atari games found earlier this year for sale on eBay and on the council's own website.

The mystery behind who dumped the games in the landfill, and why, inspired the dig and a documentary film by Microsoft Corp's Xbox Entertainment Studios.
