Crossbell from the Trails saga.
But why you ask? It's a modern looking comercial hub!
It's also a zone of perpetual territorial disputes between two military super powers, has bootleg italian AND Chinese mafia and is also the fulcrum of some weird as fuck cult and their weird fucking rituals.
As of the latest game, MAYBE it's finally become a calm place, but I swear it is fucking cursed.
Liberl seems pretty chill on the other hand if one ignores the Aureole incident... and the Eryn village also seems lovely if boring.
Other place that is more obviously wretched is the Remote City near the Plain of Sorrow in Vandal Hearts. You wake up one morning, take a stroll, some freak event opens a rift in time and you are dropped into this hell on earth and even if you manage to reach the only place with a settlement, odds are you will just try to end it all through liver failure.
Last vote goes to the Magic Kingdom in Chrono Trigger. Place has some strong 1984 vibes. As long as you play ball and don't fuck around, seems great (till the collapse), but god forbid you can't follow those rules.
