In general, Fontaine is kind of feces in terms of atmosphere. The environment in general in the plot as if not involved, just scenery. I can't feel France. Where are the strikes, the trade unions, the class struggle? It feels like Sumeru, where scientists eat air, and where they take money for research - and the dick knows. Here Inadzuma, although it was feces, but there was a real atmosphere, such a gloomy one. Everyone's down, fucked up, starved. Samurai use their money to feed peasants, to fuck with each other, to fuck with the archon. The end was drained into the toilet, but still.
Maybe there's something about Fontaine's side quests, but I haven't done them yet. In general, it is flat somehow and the emphasis is on the heroes, and the environment is not involved in the plot.
