Pokémon being used for war efforts is prime South Park material, too bad they already did that.

A game aimed at children supporting military intelligence is prime cyberpunk material. No doubt fiction beat us to that as well.

Sure did.. it’s called Ender’s Game (Orson Scott Card).

And before that, The Last Starfighter

And before that: "The book originated as a short story of the same name, published in the August 1977 issue of Analog Science Fiction and Fact."[1]
