A strange little side quest
The fun part of looking behind Subway Clash 3D is seeing how many older ideas are still alive in modern play. Boxing was part of the ancient Olympic Games by 688 BC, long before gloves, weight classes, or timed rounds existed in anything like their modern form. That old idea kept changing rather than disappearing. Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. Grombi files that under: small game, surprisingly large backstory.
