A strange little side quest
If Top Shootout: The Pirate Ship sends you down a curiosity rabbit hole, start here. Space Invaders arrived in 1978 and helped turn electronic games from an arcade curiosity into mainstream entertainment. And then there is this: 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.
