Remember that time everyone aboard The Enterprise starts playing that addictive game that Commander Riker picked up on Risa (along with, I’m certain, any number of STDs)? Synopsis of s06e05 here.
It was a Trojan Horse designed to mind-control the crew and it damn near succeeds, except for the fact that Wesley Crusher is skeptical refuses to play. This gives him enough time to fix Lt. Data who was scuttled by a saboteur. Wesley is eventually held down and forced to play the game. But then Lt. Data arrives, strobes some light around the ship, and saves the day.
Now I’m not saying Pokémon Go is a Ktarian scheme to take over the world. But I’m not saying it isn’t, yet.
