A strange little side quest
The fun part of looking behind Tetrix 3D is seeing how many older ideas are still alive in modern play. Formula 1 introduced pit-lane speed limits during the 1994 season as safety concerns grew around increasingly fast cars and busier pit lanes. The same trail leads to another fact: Midway's Gun Fight from 1975 was the first arcade video game to use a microprocessor. The details change, but the appeal of learning a system and trying again is remarkably persistent.
