Easiest Video Game of All Time
Smurf 1982

ColecoVision was a 1982 state of the art console video game machine.

Smurfs: Rescue in Gargamel's Castle is a ColecoVision game that could be beaten within 3 minutes after taking the cartridge out of the box.  This video basically shows all there was to the game - a jump, double jump, and a duck.

Sadly when playing this game - it attracted a crowd and we were all impressed by the stunning graphics.
