>>16220388>unova's theme is new york. kalos theme is franceThat's true, but it's not a theme that connects all parts of the regions and makes them whole. How should I explain this, so the problem is that Kalos and Unova are not aesthetically consistent. They have something that is there in the dialogue, NPC and pokemon designs, and to a lesser degree in the city designs as well, although I'd argue that only one city in each game makes it apparent.
However look at the map of, let's say Kalos, and try to find examples of how its theme (France) shows on area design. For the most part, it doesn't. The theme is simply not there in the overworld.
