just look at PLA, which is basically Sinnoh reimagined in full 3d scale comparable to the current gens. it has one (1) single town, and 5 areas with assets that look like a gamecube game (I like PLA, but it's true). now imagine if they had to make assets for 13 other cities (not including the battle zone), plus dungeons, a variety of routes, and more. it would be an utter disaster.
gamefreak (or the companies they outsource to) just don't have that kind of game in them, you can see it in how rushed and sloppy the main series is. people need to stop acting like this is uniquely a problem with BDSP and not the Pokemon franchise as a whole. if you still expected anything like that concept art after playing LGPE, SWSH, PLA etc, you might just be retarded.
