- a game played by electronically manipulating images produced by a computer program on a television screen or other display screen.
This can be Street Fighter, Halo, even Flappy Bird. There is no need to argue what a video game is when everyone knows full-well what exactly comprises a video game. A game could be utter nonsense, and have no purpose, yet it still focuses on a player tasked with beating whatever challenge set before them, regardless of story and gameplay.
A mobile port of Tic Tac Toe would still be considered a video game.
Thus no one needs long ramblings of pseudo-intelligence to try to justify one's opinion on what makes a video game a video game.
