It's not the most graphically impressive area, but god damn if it isn't the most beautiful and striking I've seen all gen.
the contrast this decaying, yet serene place with it's weird as fuck inhabitants has compared to the rest of the game is something else.
It's a shame Sekiro's replayability is not it's strong point and that it's one of the last areas in the game, so I probably won't see it as often on my own screen ingame, but yeah. Whoever the people were who came up with the concept, art and implementation, I love you.
