A strange little side quest
A small trivia drop for Blocker: Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares. A second detail makes the picture even better: Street Fighter II, released in 1991, turned head-to-head arcade fighting into a worldwide phenomenon and helped define the modern fighting-game genre. It is a good reminder that simple game mechanics can carry a surprising amount of history.
