A strange little side quest
Exo may feel immediate, but the ideas around strategy games have been evolving for a very long time. The word 'checkmate' is linked to the Persian expression 'shah mat', used when the king was trapped. Another piece of context lands nicely beside it: Space Invaders, released in 1978, helped push video games into mainstream popular culture. That is the kind of background detail that makes another attempt at Exo feel a bit more connected to the history of play.
