The Coleco company created over 50 games for their Colecovision system. At the launch, most games were converted arcade games. Later, the developped their own games in addition to creating games based on movies and toys.
Most of the games are easy to find. Coleco is the only company that made overlays. Some of them were meant for standard controllers and others for the Super Action Controllers. Canadian games were equipped with additionnal French labels. Some American games were in plastic boxes (clamshell) while the Canadian version of the same games were in cardboard boxes.
Unfortunately, the catalogue showed many games that were never released. It was a company strategy in order to see future consumer interest.
