Could you explain what you mean by this? I genuinely don't understand this statement, I can't make sense of it. Are you saying that Detroit asked Quantic Dream (who are a French company based entirely in France) for this or something?
Detroit was also the main hub in Deus Ex: Human Revolution. Home to Sarif industries, the leading human augmentation/ cybernetics company in the franchise, so it's not like it's a city lacking exposure in video games. Is this something to do with american cars or something? I'm at a complete loss.
Oh, well
Detroit has a really big history of its collapse. It was a hub of the automotive industry that boomed during that time, and later collapsed, currently having an unemployment rate that's the highest in the US at around 23%, and having had its population drop just 60% since the 1950s from about 1.8 million to around 700,000, and being huge in crime and poverty.
Because of that history, it makes for a good setting for a lot of fictions -
RoboCop probably being the most immediately famous, but
Only Lovers Left Alive is a recent one that I enjoyed for similar reasons for how it was used. Suffice to say that the setting itself has kind of built up a lot of metaphor when dealing with technology-driven industry and class issues (likely why was used in
Deus Ex), which is why you'll see it used when and where you do.
Plus, aside from the obvious elements that that provides for a setting, that setting exposure -- let alone this where they're completely naming the game after it -- is probably nothing but good for them, and I imagine any negotiation that you'd have to do to name a game after a real-world city wouldn't've been difficult for those reasons.
tl;dr - It mostly has to do with the actual history of the city itself.

Was the what the simpsons were parodying in their itchy and scratchy land eps?
