A strange little side quest
If Tralalero Tralala sends you down a curiosity rabbit hole, start here. Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. The same trail leads to another fact: Pong was field-tested in California bars in 1972 and helped launch the modern arcade-game era. That gives Tralalero Tralala a little more company than it first appears to have.
