FIFA, the video game that has actually changed the culture of the game it is simulating (and not always for the better):
The data Fifa draws upon has become so accurate that teams have started to use the game to scout for potential new signings or to test out the strengths and weaknesses of upcoming opponents. The Arsenal midfielder Alex Iwobi recently told the New York Times that when he was starting out, if a player he had never played against was on the other team, he would “look at his name and then try to remember how good he was on Fifa”. In October 2013, Leyton Orient’s manager introduced a no-Fifa-before-a-match-day policy, after members of his team stayed up late rehearsing the next day’s fixture (which they subsequently lost).
Also, how an American company ended up building the best-known game about a decidedly non-American sport: “I mean this respectfully, but the reason Fifa is so successful is that the game was developed and published a long way from head office.”
