A strange little side quest
One reason strategy games keeps producing good game ideas around Ars Dei 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. The same trail leads to another fact: Midway's Gun Fight from 1975 was the first arcade video game to use a microprocessor. That gives Ars Dei a little more company than it first appears to have.
