A strange little side quest
Before the next round of Ghostly Rainkeeper, here is a piece of the bigger picture. Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares. The timeline takes another interesting turn: Spacewar! appeared on MIT's PDP-1 in 1962 and became one of the earliest influential computer games shared among programmers. That is the kind of background detail that makes another attempt at Ghostly Rainkeeper feel a bit more connected to the history of play.
