A strange little side quest
Between one round of The Irish Baby Rifleman and the next, this is worth knowing: Gun Fight reached arcades in 1975 and became the first arcade video game to use a microprocessor. The broader history adds one more wrinkle. Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. That history is one reason familiar mechanics can still feel new when they are recombined well.
