A strange little side quest
The next time Sift Heads World Act asks for one more try, remember that game ideas rarely appear from nowhere. Space Invaders arrived in 1978 and helped turn electronic games from an arcade curiosity into mainstream entertainment. Another piece of context lands nicely beside it: Atari's Gran Trak 10 from 1974 is recognized as the first arcade racing video game. That history is one reason familiar mechanics can still feel new when they are recombined well.
