A strange little side quest
One reason strategy games keeps producing good game ideas around War V: Path of the Survivor is that its history is full of strange turns. The word 'checkmate' is linked to the Persian expression 'shah mat', used when the king was trapped. There is another connection worth keeping in the same mental pocket: 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.
