A strange little side quest
Call of Ops has plenty of company in a long tradition of players chasing timing, patterns and better decisions. Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. A second detail makes the picture even better: Pong was field-tested in California bars in 1972 and helped launch the modern arcade-game era. That is the kind of background detail that makes another attempt at Call of Ops feel a bit more connected to the history of play.
