A strange little side quest
The mechanics around Xochipilli's Trade have roots that stretch far beyond modern browsers. By 1987, fantasy role-playing had become a major computer-game direction, with Zelda, licensed Dungeons & Dragons games and other story-led adventures expanding the form. It also connects to a different milestone: Pac-Man went on sale in 1980, and its creator Toru Iwatani famously linked the character's shape to a pizza with a slice missing. It is a good reminder that simple game mechanics can carry a surprising amount of history.
