Hmm... I think the setting of Problem Sleuth
would be pretty cool. Kind of dangerous, but Death Is Cheap
and everything's all cool and Film Noir
-esque without the bleakness of an actual film noir. Plus, imagination-based powers.
Other possibilities that I'd rate pretty high would be the Mushroom Kingdom
and Gunnerkrigg Court
. Maybe the Wizarding World
, though that's got some very disturbing elements and I wouldn't want to live there prior to Voldemort's demise.
I think fantasy settings, on average, tend to be less dystopian than science fiction settings. Some fantasy settings are positively idyllic (the setting of The Wind in the Willows
springs to mind, and to a lesser extent the aforementioned Equestria and, for that matter, large parts of Middle-Earth). However, that's not necessarily perfect; I think living as an animal from The Wind in the Willows
would get boring fast, unless you happened to be Mr. Toad.
