A strange little side quest
The fun part of looking behind Spect is seeing how many older ideas are still alive in modern play. Humans did not see the Moon's far side until a Soviet spacecraft flew past it in 1959. Another piece of context lands nicely beside it: Space Invaders arrived in 1978 and helped turn electronic games from an arcade curiosity into mainstream entertainment. That history is one reason familiar mechanics can still feel new when they are recombined well.
