A strange little side quest
A small trivia drop for Missile Madness: SimCity grew out of Will Wright's enjoyment of the map editor he had built for an earlier game; the act of shaping a city became the game itself. That old idea kept changing rather than disappearing. Chess changed dramatically in Europe during the 15th and 16th centuries when the queen became the board's most powerful piece. The details change, but the appeal of learning a system and trying again is remarkably persistent.
