Galactic Attack (TRS-80 Color Computer)
Radio Shack had a confusing array of similarly named, incompatible computers. The Color Computer (of which there were three models, each of which was mostly backwards compatible) was probably the most successful. There were a wide variety of games released for the Color Computer though most were marketed by Radio Shack themselves and were highly derivative of other popular games. They weren’t necessarily of low quality (though many were) but most were clones of more popular games of the time.
