I have the following to trade (all include cart, box and manual except where noted):

Asteroids (Sears)

Battlezone
Breakaway IV (Sears)
Chopper Command
Combat
Communist Mutants from Space
Demon Attack - w/ outer box only (missing plastic insert)
Fireball
Funky Fish (reproduction of unreleased prototype)
Kaboom!
Laser Blast
Night Driver (Sears)
Pick 'n Pile (PAL)

Space Attack
Space Invaders
Space Jockey
Star Raiders (Sears) - w/ outer box, one inner box, manual, Atari Force #3 comic, Video Touch Pad and overlay

I'm looking to trade for other boxed Atari 2600 games, or we can just swap empty boxes, that works too. I still need lots of common and uncommon boxes (don't just go by my want list) so let me know what you've got and I'll let you know if I need it.
