Whatever country they're meant to be set in, it might as well be the same flavorless suburb in the Central Valley of California that all the sitcoms exported from America seem to be set in. If you don't make use of a location's uniqueness, it's pretty much irrelevant, IMO.
Hell, I don't even necessarily need a game set in Turkey to be interesting. Just get *out* of the suburb! Leave your siblings alone-there's much cooler people to fuck! Set it on a ship in the doldrums at sea! Set it deep in the countryside! Set it in an FOB in a country at war!
Or maybe it's just that the audience has bad taste. After all, what does my whining and bleating matter if a new developer sees Summertime Saga making a truly *hilarious* amount of money and wants to try and replicate that for themselves?
