Only one that looks true to game is Mideel. Wall Market isn't shitty enough, as in it's supposed to look like shack clutters set up here and there, not Chinatown. If anything, it's more akin to a carnival/swap meet left to ROT in the darkness on a fairgrounds. Sector 5 Slums are supposed to be built within the scattered debris and crap on the ground, not favela-type structure in a large carved out pipe. Both locations (hell, most of the Slums) takes place on the dirt ground, very little paved streets and walkways (and if they are, the streets are FUCKED UP). These art pieces glam up the locations considerably, but these locations in the slums aren't supposed to be glamorous or cool architectural marvels. They are places people are FORCED to live in. Probably the most glamorous locations in the slums are the church and Aerith's house.
