Criteria

This article only looks at official licensed games. As much as I respect homebrew projects, they won't be considered. Only games released in the United States are listed as well. Systems had different life spans in different countries so I had to settle on one.

Basically if you couldn't walk into a game store in the US and buy a copy, it's not on the list.

This also leaves out the Telegames and Songbird Productions games, most of which were manufactured after a system's demise and only available via mail order. I'm sure some readers won't be happy with this but I had to apply a standard.

There are obviously some systems missing from this list. See the Missing Systems section for a more detailed explanation on these.
