"Extra Terrestrial" game cartridge

"Extra Terrestrial" game cartridge is a junk item in Wasteland 2.

Description
Who would bury all these perfectly good game cartridges?

Preliminary Assessment
If you take all of these you will be encumbered and unable to move on a local map. They are actually worthless.

You can trade a single one in Quarex's Arcade in Rail Nomad for 1,000 scrap and a Clay Wizard Figurine.

A reference to Atari who claimed to have buried around 700,000 game cartridges for the Atari 2600 console (including E.T. and other games), in a landfill in New Mexico (Alamogordo) in 1983.
