A strange little side quest
For Duck's Sake may feel immediate, but the ideas around action games have been evolving for a very long time. 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: Modern chess traces back to the Indian game chaturanga, recorded around the sixth century and built around pieces representing parts of an army. That gives For Duck's Sake a little more company than it first appears to have.
