My interest has been focused on games that I pored over in the catalogs when I was a kid - Atari, Activision, Imagic, and Parker Brothers. I can play the other 3rd stuff on the Harmony, but its these common carts that resonate most for me. If collected, I try to get the label version from the era of release. As a wild card, there are a bunch of AA titles thrown in there - hacks and homebrews.
This album is dedicated to showing Atari 2600 games collection. Mainly focused on undiscovered and rarity games. All pics taken by me, Hope you enjoy all pictures and thanks for visiting :) www.atari2600collect.com
