A strange little side quest
Zoom out from Soul-O for a moment and the timeline gets surprisingly deep. The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. And then there is this: 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. That gives Soul-O a little more company than it first appears to have.
