The Q&Q CG-003 Fisherman — LCD Fishing Game
The Q&Q CG-003 Fisherman was a handheld LCD fishing game — one of the many simple pocket gaming devices produced throughout the 1980s for the budget end of the handheld market. Q&Q was a brand associated with Citizen Watch Company, the Japanese watchmaker that also produced consumer electronics. Fishing-themed LCD games were popular in the early 1980s, with the patience and timing mechanics of fishing translating naturally to the simple input model of handheld LCD gaming. These budget devices offered affordable portable entertainment through toy shops and general retailers at prices accessible to children and families.
