A strange little side quest
Between one round of Vampire Manor and the next, this is worth knowing: Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares. That old idea kept changing rather than disappearing. Pong was field-tested in California bars in 1972 and helped launch the modern arcade-game era. The details change, but the appeal of learning a system and trying again is remarkably persistent.
